Here is a real sample from Chapter 5 (Percentages) and Chapter 6 (Profit & Loss).

Shortcut: multiplier method

Q. A price rises 20%, falls 10%, then rises 25%. Net change?

Multipliers: 1.20 × 0.90 × 1.25 = 1.35
Answer: 35% increase
Convert every change to a multiplier. It is faster and safer for 3 or more steps.

Trap: equal SP, equal %

Q. Two articles sold at ₹1,200 each, one at 20% profit, one at 20% loss. Overall?

Total CP = 1,000 + 1,500 = 2,500; Total SP = 2,400
Answer: 4% loss (= x²/100)
Equal profit % and loss % at the same SP is always a loss. Never pick “no profit, no loss”.

Questions, answered

Is this for beginners?

It is a revision workbook, not a full course. It assumes you have studied the concepts once. If you are starting from zero, use it as a map of what to learn, then come back to it before the exam.

Will it help for my exam?

If your exam tests arithmetic, algebra, geometry or data interpretation, yes. That covers SSC, banking, railways, CAT and other MBA tests, UPSC CSAT, defence and many state exams. Always check your exam’s latest official syllabus.

Are the examples from past papers?

No. They are original, exam-style examples written to teach each shortcut.

How do I get the book?

It is a PDF. You get the download link right after payment and can read it on any device.

Can I share it with friends?

Please don’t. The book is copyrighted. Ask your friends to buy their own copy for ₹49.

Can it guarantee a score?

No book can. This one helps you revise smarter in the final hours. Your results still depend on your practice and preparation.
