Tailored for SSC CPO Quantitative Aptitude. 4 active practice questions. Related topics: Percentage, Profit and Loss, Simple Interest.

SSC CPO approach: For SSC CPO, approach this topic with disciplined elimination and controlled execution. Decide first what information is relevant before committing to calculation, grammar transformation, or visual reasoning.

What to master: Master question classification, option elimination, and clean setup. Practise distinguishing genuine complexity from distractors designed to consume time.

SSC CPO focus:

Prepare for SSC CPO with disciplined selection, fast elimination, and accuracy across objective Tier-I patterns.

Attempt strategy: For SSC CPO, recognise the question pattern before calculating, eliminate impossible choices early, and keep enough time for a final accuracy check.

Revision path: CPO revision: concept trigger -> elimination method -> timed application -> mistake log.

SSC CPO exam emphasis for Algebra

CPO emphasis: recognition, elimination, controlled speed, and avoiding distractor-driven errors.

Most important error to avoid

Typical CPO loss comes from acting before reading the full requirement, missing an eliminable option, or committing too early to a calculation-heavy route.

SSC CPO Algebra — CPO selection plan

Approach this topic with disciplined option and method selection. Decide what information matters before committing to calculation or transformation. For Algebra, concentrate on identities, linear relations, simplification, substitution, factorisation, sign handling, and equation balance.

How to practise this topic

Mix direct questions with distractor-heavy variants and practise eliminating impossible choices before doing full work whenever the structure permits. A reliable drill sequence is to classify the expression or equation, choose identity, factorisation or substitution deliberately, simplify stepwise, and substitute back when verification is practical.

Mistakes to remove before the next set

Watch specifically for sign errors, invalid cancellation, applying an identity in the wrong form, or expanding when a shorter substitution is available. During review, separate recognition errors from execution errors. Rework questions where an earlier elimination or clearer setup could have saved time.

Summary Formula Tricks Mistakes Solved Example Practice FAQ

Algebra revision for SSC CPO: understand the base rule, apply the correct formula or relation, check common traps, then practise with approved questions.

Algebra converts numerical relationships into equations using variables. For SSC arithmetic, focus on identities, linear equations, factorisation, simplification and translating word statements into algebraic form.

The key exam skill is to identify the unknown, form the shortest valid equation and simplify without losing signs.

SSC CPO focus: Solve the core method first, then use the approved practice questions on this page to build exam-speed accuracy.

Algebra revision rule: concept → formula/relation → one worked example → timed practice → error review.

Core concept
Key formula/relation
Common trap
Approved practice

(a+b)² = a²+2ab+b²
(a-b)² = a²-2ab+b²
a²-b² = (a-b)(a+b)
If ax+b=c, then x=(c-b)/a, a≠0.

Before expanding expressions, check whether an identity or factorisation gives a shorter route. In MCQs, substitute simple values only when the expression allows it logically.

Learn the shortcut first

Shortcut before you solve

Algebra becomes faster when you identify the structure before doing arithmetic.

Faster solving steps

Use this 4-step method before solving to keep your thinking fast and repeatable.

Step 1 Identify relation

Spot the pattern, relationship, or core idea first.

Step 2 Apply same pattern

Use the same rule instead of re-solving from scratch.

Step 3 Eliminate wrong options

Remove confusing choices before comparing the last few.

Step 4 Confirm final answer

Pick the option that matches the shortcut most cleanly.

Now apply the trick on real questions

Use the shortcut above before solving these questions

Translate the relation into the shortest equation, then simplify before substituting values.

Tip: Check whether an identity, factorisation, or simple linear equation is faster than expansion.

Step 1

Subtract 5 from both sides: 3x = 15.

Step 2

Divide by 3: x = 5.

Rule

Perform the same valid operation on both sides of an equation.

3-second trick

Isolate the variable before doing anything more complicated.

Trap to avoid

Do not change signs without applying the corresponding inverse operation.

Correct answer

Thinking path

Move the constant term first.
Reduce the coefficient of x.
Verify in the original equation.

Final answer: 5

Why this is fast: A linear equation is quickest when the variable is isolated step by step.
