FAQs on Practice Questions Level 1: Percentage - 1

1. How do I calculate percentage increase and decrease in CAT-level problems?
Ans. Percentage increase equals (New Value - Old Value) / Old Value × 100, while percentage decrease follows the same formula with the new value being smaller. For CAT quantitative aptitude, mastering these formulas helps solve profit-loss and population growth problems quickly. Practice with real exam scenarios to build speed and accuracy in percentage calculations.
2. What's the difference between percentage change and percentage point change?
Ans. Percentage change measures the relative shift from an original value using the percentage formula, while percentage point change shows the absolute numerical difference between two percentages. If profit margins rise from 20% to 25%, that's a 5 percentage point increase but a 25% relative increase. Understanding this distinction prevents common CAT exam mistakes.
3. How do I solve compound percentage problems where multiple percentage changes happen one after another?
Ans. Apply successive percentage changes by multiplying the multipliers rather than adding percentages. If a quantity increases by 10% then 20%, the overall change is 1.10 × 1.20 = 1.32, representing a 32% total increase. This method eliminates calculation errors in layered percentage problems common in CAT quantitative reasoning sections.
4. Why do I keep getting wrong answers when solving percentage-based profit and loss problems?
Ans. Most students calculate percentages on the wrong base-always identify whether the base is cost price, selling price, or marked price before computing. A 20% profit on cost price isn't the same as a 20% discount on marked price. Clarifying the reference value upfront prevents this frequent error in competitive exam percentage applications.
5. What percentage shortcuts should I memorise for faster CAT problem-solving?
Ans. Learn key conversions: 50% = 1/2, 25% = 1/4, 33.33% = 1/3, and 20% = 1/5 for instant fraction-percentage switching. Memorise multipliers like 1.2 for 20% increase and 0.8 for 20% decrease to skip mental division during exams. These mental maths tricks dramatically accelerate percentage calculations in time-constrained CAT sections.
