SSC shortcut tricks

Divisibility, remainders, unit digits and factors

• ⚡ Floor-division counting. Count multiples of k up to the end of the range, then subtract the multiples before the start. No listing needed. Number types, place value & counting →
• ⚡ Place value in one product. Place value minus face value equals digit times (position value minus 1). The 9999 pattern does it in one line. Number types, place value & counting →
• ⚡ Middle term times count. For any evenly spaced list, the sum equals the number of terms times the middle term. The middle term is the average of first and last. Number types, place value & counting →

Solve long calculations fast using BODMAS and shortcuts

• ⚡ Bracket every 'of'. Rewrite each 'of' as a bracketed product before doing any division. The bracket makes the grouping visible and kills the trap. BODMAS, 'of', brackets & vinculum →
• ⚡ Continued fractions from the bottom. Simplify the deepest fraction first, invert it, add the next layer, and repeat upward. BODMAS, 'of', brackets & vinculum →
• ⚡ Digit-sum check. Casting out nines: digit sums must match on both sides of the equals sign. It kills wrong options without computing the product. BODMAS, 'of', brackets & vinculum →

Highest common factor and lowest common multiple

• ⚡ Ratio split. Numbers in ratio a : b (co-prime parts) with HCF h are ha and hb. LCM = h times a times b; sum = h times (a plus b). HCF & LCM: definitions and core relations →
• ⚡ Product divided by HCF. Given any two of product, HCF, LCM, the product relation settles the third in one division. HCF & LCM: definitions and core relations →
• ⚡ Co-prime pairs from the quotient. For pair-count questions, divide the product by the square of the HCF, then count co-prime factor pairs of the result. HCF & LCM: definitions and core relations →

Percent basics, increase/decrease and fraction values

• ⚡ Let the fraction table do the division. Replace the percent with its fraction from the table. 12.5\% becomes \dfrac{1}{8}, so the sum turns into a simple division. Percentage meaning & conversions →
• ⚡ Build the percent from 10% and 1% pieces. Move the decimal point for 10\% and 1\%, then add pieces. Works without pen-and-paper multiplication. Percentage meaning & conversions →
• ⚡ Swap x% of y into y% of x. x\% of y always equals y\% of x. Swap when one side turns into a friendly percent. Percentage meaning & conversions →

Ratios, proportions, partnership and ages

• ⚡ x solves everything. Translate 'ratio a : b' into ax and bx. Every extra fact becomes one small equation in x. Ratio basics & dividing amounts →
• ⚡ LCM bridging for three terms. Scale A : B so its B-term matches the B-term of B : C, then read off A : B : C. Ratio basics & dividing amounts →
• ⚡ One share known, get the rest. Share = fraction × total. Recover the total from one share, then build any other share. Ratio basics & dividing amounts →

Average of a group, and what changes when people join or leave

• ⚡ Flip to the sum first. Never push averages around. Change them to sums, adjust, divide back at the end. Average & the sum bridge →
• ⚡ Same operation on every value. Do to the average exactly what is done to each value, in the same order. Average & the sum bridge →
• ⚡ Equal gaps: jump from the middle. The average of evenly spaced numbers is the middle term. Step out from it instead of adding everything. Average & the sum bridge →

Simple and compound interest

• ⚡ Cover the unknown. Write SI = \dfrac{PRT}{100} and cover the letter you want. That covered formula is the whole equation. Simple Interest →
• ⚡ n-times to rate. 'Becomes n times in T years' means the interest earned is (n-1)P. The P cancels. Simple Interest →
• ⚡ One year at a time. Divide the total interest by the years; every year carries exactly that much. Simple Interest →

Cost price, selling price, profit and discounts

• ⚡ Fraction swap for the per cent. Turn the profit into a fraction of CP and the per cent falls out. 170/850 is clearly 1/5. Profit, Loss and CP–SP Basics →
• ⚡ Divide by the chip to get CP. A loss of 4\% means the chip 96/100. Divide the SP by the chip, nothing else. Profit, Loss and CP–SP Basics →
• ⚡ Same per cent scales linearly. When the profit per cent is fixed, CP and SP scale together. Article counts often hide a clean ratio. Profit, Loss and CP–SP Basics →

Mixing two things to get a target price or strength

• ⚡ Freeze the unchanged ingredient. Water added means milk unchanged. Hang the whole question on the ingredient that does not move. Mixture Concentration & Amounts →
• ⚡ Rebuild the per cent after dilution. Milk is fixed, the total grows — divide again. Mixture Concentration & Amounts →
• ⚡ One ratio change, one equation. Set the frozen ingredient against the wanted ratio and solve for the addition. Mixture Concentration & Amounts →

Work done together, efficiency, and pipes filling tanks

• ⚡ LCM units, not fractions. Set the job to the LCM of the individual times; every rate becomes a small whole number. Work Rates & the LCM Method →
• ⚡ The ab over a+b reflex. For exactly two workers, one formula — no fraction addition at all. Work Rates & the LCM Method →
• ⚡ Three workers through the LCM. Same method with three rates added in one line. Work Rates & the LCM Method →

Trains, boats, relative speed and average speed

• ⚡ Convert first, always. Train lengths are in metres, times in seconds — reach m/s before anything else. Speed, Distance, Time & Unit Conversion →
• ⚡ Harmonic mean for round trips. Same distance out and back → 2ab/(a+b) in one line. Speed, Distance, Time & Unit Conversion →
• ⚡ Early and late gaps are time equations. Both runs cover the SAME distance — equate or subtract the two time expressions. Speed, Distance, Time & Unit Conversion →

Identities, equations and simplifying algebraic expressions

• ⚡ Build higher powers from a sum and a product. Chain the rungs: square-sum first, then cube-sum, then fourth powers. The individual letters are never needed. Basic algebraic identities →
• ⚡ Recognise the identity inside decimals. Cubed decimals over a trinomial mean a cube identity. The value is the sum or difference of the bases. Basic algebraic identities →
• ⚡ Value-putting among expression options. Put small numbers into the question and each option. Wrong options die in one round; ties die in a second. Basic algebraic identities →

Lines, angles, triangles, circles and polygons

• ⚡ Say the shape, then the rule. Trace the two angles with your finger. An F or Z shape means they are equal. A C shape means they add to 180^\circ. Lines and angles →
• ⚡ Supplement minus complement is always 90. Whatever the angle, its supplement and its complement differ by exactly 90^\circ. Use it as a free check, or to build the equation. Lines and angles →
• ⚡ Centre angles from one input. Only \angle A is needed. Read which centre the question names, then use its formula. Triangles and their centres →

Area and perimeter of flat shapes

• ⚡ Triplet beats Heron. Before Heron, check for a triplet. A right triangle needs only half the product of its legs. Areas of triangles →
• ⚡ Isosceles: half it first. The median to the base is the height. Halve the base, then use Pythagoras with an equal side. Areas of triangles →
• ⚡ Two radii from Heron. After Heron gives the area, both radii are one division away: r divides by s, R uses abc over 4K. Areas of triangles →

Volume and surface area of solid shapes

• ⚡ Cubes table, not cube roots. Know the cubes to 12 by heart. Reverse questions become look-ups: 343 is 7 cubed. Cube and cuboid →
• ⚡ Capacity: metres to litres. Compute the volume in cubic metres, then multiply by 1000 for litres. Never by 100. Cube and cuboid →
• ⚡ Edge scaling in powers. Edge times k: surface times k squared, volume times k cubed. Doubling is 4 and 8. Cube and cuboid →

Trig ratios, standard values and identities

• ⚡ The root-k-over-2 row. sin at 0, 30, 45, 60, 90 is root-0, root-1, root-2, root-3, root-4, all over 2. Cos is the same row reversed. Ratios and standard values →
• ⚡ Triplet finishes the ratios. Given sin = 3/5, place 3 and 5 in the triangle; the third side 4 completes 3-4-5 and every ratio follows. Ratios and standard values →
• ⚡ Angle from a value. Isolate the ratio, then match the table entry. 2 sin = root 3 means sin = root-3 over 2, the 60-degree slot. Ratios and standard values →

Find heights and distances using angles

• ⚡ Swap depression for elevation first. Never work with a downward angle directly. Redraw it at the bottom of the tower and solve an ordinary elevation question. Angles of elevation and depression →
• ⚡ Shadows without trigonometry. Same sun, same time, similar triangles. Set up the stick ratio and multiply; no tangent needed. Angles of elevation and depression →
• ⚡ Forty-five degrees means equal legs. Whenever the angle is 45^\circ, the height above the eye equals the horizontal distance. Write the equal pair without any tangent. Angles of elevation and depression →

Mean, median, mode and range

• ⚡ Deviations from a round base. Pick a round number near the values. Add the small differences and divide by the count. The base can be anything. Mean, weighted mean and combined mean →
• ⚡ Watch where the average is pulled. The combined average always lies between the two group averages, closer to the bigger group. Use this to reject impossible options in seconds. Mean, weighted mean and combined mean →
• ⚡ Count positions, do not hunt. For odd n, the median sits at position (n+1)/2 of the sorted list. Count to that position instead of scanning for the middle by eye. Median and mode of raw data →

Answer questions from tables, bar graphs and pie charts

• ⚡ Sweep the row with tick marks. For count-type questions (how many years above a value), tick the qualifying cells while reading once. No rewriting, no calculator. Reading tables: totals, differences, ratios →
• ⚡ Column-first for year questions. Any question about one year (best year, total of a year) lives in a single column. Add that column alone; ignore the rest of the table. Reading tables: totals, differences, ratios →
• ⚡ The 1% probe. Find 1% of the base first; then any percentage is that times n. 1% of 250 is 2.5, so 70 units is 28%. Percentage change and comparisons →

Selections, arrangements and chance — the modern-maths block shared by SSC, Banking and CAT papers. The topic is small, but a handful of repeating patterns (word arrangements, committees, bag draws, two-dice sums) make its marks near-guaranteed with a little practice.

• ⚡ Fill the restricted slot first. Even numbers, numbers ending in 5, no leading zero — the condition always lives in one slot. Fill that slot first, then the rest. Counting Principles: Product & Sum Rules →
• ⚡ AND multiply, OR add — say it out loud. Read the question and underline the joining words. 'And' multiplies counts; 'or' adds cases. Most counting errors are one wrong joining word. Counting Principles: Product & Sum Rules →
• ⚡ Block method for 'together'. Tie the must-together people into one bundle. Arrange the bundle with the others, then arrange inside the bundle. Permutations: Arrangements →

Progressions are lists that follow a fixed rule: APs add a constant, GPs multiply by one, HPs hide an AP in their reciprocals, and special series come with ready-made sum formulas. Alongside term-pattern sequences, this block gives a quick mark in SSC, Railway and Banking papers and anchors the series questions of CAT algebra.

• ⚡ The middle term is the average. For an odd count of AP terms, sum = middle \times count. One division gives the middle term, and one multiplication gives the sum. Arithmetic Progressions →
• ⚡ Equidistant terms add to the same value. a_2 + a_{15}, a_1 + a_{16} — pairs placed equally far from the ends share one sum. A sum of all n terms then needs no a or d at all. Arithmetic Progressions →
• ⚡ Name three terms a-d, a, a+d. Three consecutive AP terms collapse to one unknown a plus d. Sum gives a at once; product or another condition then gives d. Arithmetic Progressions →

Sets, subsets and Venn diagrams: two- and three-group survey counting shared by SSC, Railway, Banking and CAT papers. A handful of formulas — union, inclusion–exclusion and max–min bounds — solve nearly every question. Most errors come from misreading regions, not from hard algebra.

• ⚡ Know powers of 2 by heart. Subset questions are pure powers of two. Learn 2, 4, 8, \ldots, 512 and every variant (proper, non-empty) becomes a one-step subtraction. Sets, Subsets & Power Sets →
• ⚡ Count what you do not want. For 'at least one of these elements' or 'non-empty proper', count the unwanted subsets and subtract from 2^n. Sets, Subsets & Power Sets →
• ⚡ De Morgan turns the question into one union. n(A' \cap B') looks scary. De Morgan converts it to n(U) - n(A \cup B), a two-line count. Sets, Subsets & Power Sets →

Function notation, graphs, modulus and logarithms — the algebra engine room of management exams. Banking and SSC papers meet it mainly in Tier 2 and higher-level sets, where 1–2 clean, formula-driven questions reward anyone who knows the standard moves.

• ⚡ Hunt the two troublemakers. For a domain, only two things can go wrong: a zero bottom or a negative root. Scan the rule for \div and \sqrt{}, write the condition, solve. Functions, domain & range →
• ⚡ Complete the square for range. Write ax^2 + bx + c as a(x - h)^2 + k. The square cannot go below 0, so k is the smallest (or largest) output. Functions, domain & range →
• ⚡ Test $f(-1)$ for even / odd. Compute f(-1) and compare with f(1) and -f(1). Equal means even, opposite means odd. Always confirm with the full rule f(-x). Functions, domain & range →

Find the pair that follows the same relationship

• ⚡ Say the link first, read the options second. Turn the full pair into a sentence before you look at the options. Then test each option with that same sentence. Options that are only from the same… The idea of analogy →
• ⚡ Subtract once, then copy the pattern. Write one row of subtractions for the model pair. The pattern you get is the rule. Apply the same pattern to the third group and read the letters… Letter / letter-cluster analogy →
• ⚡ Spot opposite letters by the 27 total. If matching letters of the model pair add up to 27, the rule is opposite letters. Then write the opposite of each letter. No counting is needed. Letter / letter-cluster analogy →

Find the odd one out

• ⚡ Write the majority rule, not the exception. Instead of hunting the odd item, write the rule the other three follow. Confirm each of the three obeys it and the last one breaks it. This stops you… The idea of odd one out →
• ⚡ Category first, then a binary property. First find the broad category shared by three words. If the fourth also fits that category, switch to a binary property: salt or fresh, input or… Word odd one out →
• ⚡ Last-digit scan for squares. Squares end only in 0, 1, 4, 5, 6 or 9. An option ending in 2, 3, 7 or 8 cannot be a square. For the rest, place the number between two known squares. Number odd one out →

Find the next or missing term in a number or letter series

• ⚡ Two rows of gaps in ten seconds. Write the gaps under the series. If they are not equal, write the gaps of the gaps. Stop when a row is clear. Then work back up. How every series is cracked →
• ⚡ Say the rule aloud in words. Before you calculate, say the rule in one plain sentence, like 'add 3, then add 6, then add 9'. If you cannot say it in a sentence, the rule is wrong. How every series is cracked →
• ⚡ Ratio test before anything fancy. Divide each term by the one before it. If the result is close to 2 or 3, try ×k ± r. Find r from what is left over. Number series →

Crack the code rule and apply it to a new word

• ⚡ Find the difference list first. Write the sample word above its code. Subtract the positions slot by slot. The list of differences is the rule. Apply the same list to the new word. The coding-decoding family →
• ⚡ Hop from an anchor, do not count. To shift a letter, jump from the nearest EJOTY anchor. W is Y − 2, so W + 4 = Y + 2 = A. Two small hops are faster than counting W, X, Y, Z, A. Letter shift coding →
• ⚡ Decoding: run the shifts backwards. When the code is given and the word is asked, subtract the shift instead of adding it. Letter shift coding →

Swap signs and balance the equation

• ⚡ Circle the × and ÷ first. Read the line once and circle every × and ÷. Work those pieces first. Then read the line again for + and −. Your eye lands on the high-rank work… Operator puzzles and BODMAS →

• ⚡ One rewrite for every swap. Write the swaps on the left, like + ↔ × and 2 ↔ 8. Then rewrite the expression once with all swaps applied. Evaluate. Piececemeal swapping invites… Interchanging signs and numbers →

Find the hidden number in a grid or figure

• ⚡ Test the spare row. Write your guessed rule as a formula. Test it on the second complete row. Only then use it on the row with the ?. This takes ten seconds and stops… How missing-number puzzles work →
• ⚡ Build the biggest number first. Pick the biggest number in the row. Try to make it from the smaller ones. This finds the rule faster than reading left to right. How missing-number puzzles work →
• ⚡ Build the biggest cell first. Write the biggest cell of a row. Rebuild it from the other two. This shows the rule faster than reading left to right. Grids with row (or column) rules →

• ⚡ Write each sentence as an arrow. In the margin, turn every sentence into an arrow: 'Suresh's daughter is Pooja' becomes Suresh to Pooja (F). When every sentence is an arrow, the tree… How to solve blood-relation questions →
• ⚡ Flip the word, not the tree. One tree answers both directions. Keep the drawing, swap to the mirror word: father goes to son, uncle to nephew, grandfather to grandson. How to solve blood-relation questions →
• ⚡ Start from the root. The root is the person nobody calls a child. Build downward from there. Every statement then clicks into an empty slot. Multi-statement tree puzzles →

Track turns and find the final direction and distance

• ⚡ Two-line tally. Keep one running total for East-West and one for North-South. Write West and South as minus. The two totals are the whole answer, with no drawing… Direction conventions and displacement →
• ⚡ Spot the triple. If the two net moves are 3 and 4, or 5 and 12, or 8 and 15, or 7 and 24 (or their multiples), the answer is the third number. No square root is… Direction conventions and displacement →
• ⚡ Write the direction after every turn. After each turn, write one letter: N, E, S or W. Overwrite the old letter. Three written letters are safer than one long chain in your head. Direction faced and net direction →

Positions and ranks from the top or bottom

• ⚡ Check that the two ranks add to total plus 1. For one person, the two ranks from opposite ends always add up to the total plus 1. If they do not, you have misread a number. How ranking questions work →
• ⚡ Draw the end zones. Draw a short row of boxes. 'a-th from the left' means a - 1 people stand before the person. Counting people at each end is often faster than any… How ranking questions work →
• ⚡ Check that the sum of the two ranks is total plus 1. For one person, the two ranks add up to the total plus 1. Test it before you mark the answer. Ranks and positions →

Seat people in a row or around a table from clues

• ⚡ Pin the absolutes first. Ends, the middle and opposite seats fix a person outright. Fill them before you touch any chain. The remaining people usually fall into one or two… How seating puzzles are set →
• ⚡ Test one clue both ways. If you are unsure of the facing, place one clue for north and for south. The two seats differ, and this shows you which one you must use. How seating puzzles are set →
• ⚡ Chain links, do not guess gaps. 'Second to the right of A' pins B exactly two seats from A. Mark it with an arrow as soon as you read it. Most puzzles have four such arrows, and the… Single-row arrangements →

Check which conclusions follow from All/Some/No statements

• ⚡ Find the shared term. The conclusion must join the two outer terms. Find the term that appears in both statements, and ask what travels through it. What a syllogism is and how to test it →
• ⚡ One counter-picture kills it. You do not need to prove a conclusion. You need only one picture that fits the statements and breaks it. What a syllogism is and how to test it →
• ⚡ Defence lawyer thinking. For a possibility, flip your mindset. Build one picture where it holds. Done. Possibility conclusions →

Use overlapping circles to show and count groups

• ⚡ Write numbers into the regions. Do not keep numbers in your head. Write each one in its region. The answer is then a single sum. What a Venn diagram encodes →
• ⚡ Shade and compare. For a 'which expression' question, shade the phrase first. Then shade each option. Pick the match. What a Venn diagram encodes →
• ⚡ Add the four parts to check. After you fill only A, both, only B and neither, add them. If the sum is not the total, one part is wrong. Two-circle counting →

Dictionary order and alphabet position tricks

• ⚡ Find the first split point. Write the words one under another and scan the columns from the left. The first column with different letters decides the whole comparison. Ignore… Dictionary order rules →
• ⚡ Sort once, count slots. Fix one numbered order for the whole question, then answer any slot lookup from it. Re-sorting for each option is where errors and lost time come… Arranging words and picking slots →
• ⚡ EJOTY plus a tiny shift. Anchor at the nearest of E, J, O, T, Y and step from there. Position 18 is T (20) minus 2, which is R. Two seconds, no counting. Letter positions and shifts →

Decide which conclusions follow from a statement

• ⚡ The extreme-word filter. Circle words like only, all, always, never, surely, best, entire and must. If the conclusion has one and the statement does not, it almost always… Statement and conclusions →
• ⚡ Needed is not the same as enough. 'Only X can do Y' means X is required. It does not mean X is enough. Check which way the conclusion runs. Statement and conclusions →
• ⚡ The negation test. Put 'not' into the assumption. Does the speaker still have a reason to speak? If not, the assumption is implicit. Statement and assumptions →

Count triangles, squares and lines in a figure

• ⚡ Square with diagonals: 8 or 16. A rectangle with both diagonals always has 8 triangles. Add both midlines and it becomes 16. Memorise both. Counting triangles →
• ⚡ Count the lines, then choose two. In an apex figure, count the lines through the apex (extra lines plus both sides) and choose any two of them. Counting triangles →
• ⚡ Line-pair trick. A rectangle is decided by its two vertical sides and two horizontal sides. Count line pairs, never shapes. Counting squares and rectangles →

How letters and figures look in a mirror or water

• ⚡ Check the ends first. The image starts with the last character of the word, flipped. Reject options by looking at the first character only. Mirror images (vertical mirror) →
• ⚡ Symmetric-letter shortcut. A word made only of A H I M O T U V W X Y that reads the same backwards looks unchanged in a vertical mirror. Mirror images (vertical mirror) →
• ⚡ Order stays, letters go upside down. In the options, look for the one that keeps the original order and has only the unsymmetric letters turned upside down. Water images (horizontal mirror) →

Predict the pattern when folded paper is opened

• ⚡ Reflect, do not rotate. Each unfold is a mirror. The copy is at the same distance from the fold line, on the other side. A half turn of the flap is wrong. Folding and punching: unfolding the pattern →
• ⚡ Count first, then check positions. Holes = punches times layers under each punch. Use the count to remove wrong options, then check positions. Folding and punching: unfolding the pattern →
• ⚡ Doubling chain. Write 1, 2, 4, 8 as you read each full fold. Multiply by the number of punches at the end. Counting layers and holes →

• ⚡ Meaning guard. Two options are both grammatical? Choose the one that keeps the original meaning word for word. An option that changes who did what is wrong. The elimination ladder: how to choose in 20 seconds →

Pick the right word to complete a sentence

• ⚡ Answer before you look at the options. Read up to the blank and stop. Ask what the word before it usually takes. Say your answer, then find it among the options. Collocation blanks: word partnerships that decide the answer →
• ⚡ Cut options by topic. Collocation options often share an ending (-tion, -ment). Remove the ones that do not suit the topic first. A border dispute invites talks or… Collocation blanks: word partnerships that decide the answer →
• ⚡ Finish the phrase in your head. For a verb blank, turn the phrase around: 'attention is _' gives 'paid'. If your word is an option, mark it and move on. Collocation blanks: word partnerships that decide the answer →

Words with similar and opposite meanings

• ⚡ Split, then eliminate. Cut the unknown word at its joins, translate the parts you know, and remove options that clash. One sure root can remove two options. The root-word method: decode words you have never seen →
• ⚡ Learn roots as families. Learn words in root groups, not in alphabet order. The dict family: dictate, verdict, predict, contradict. The loqu family: eloquent, loquacious,… The root-word method: decode words you have never seen →
• ⚡ Warm or cold. Roots carry a feeling. Bene-, eu- and am- are warm. Mal-, dys-, phob- and mis- are cold. When stuck, pick an option with the same feeling. The root-word method: decode words you have never seen →

Three close cousins of reading comprehension, asked in banking mains and management exams: pick the best summary of a paragraph, spot the sentence that breaks a theme, or choose the line that completes it.
