FAQ
Common questions and clear answers for this topic.
Percentage means per hundred and is used to express a number as a fraction of 100. Formula: Percentage = (Value/Total Value) x 100. In competitive exams like SSC CGL, IBPS Bank PO, and CAT, percentage questions appear as: finding percentage of a number, percentage increase/decrease, percentage change, successive percentage change, and percentage in Data Interpretation.
Important percentage-fraction equivalents: 10% = 1/10, 12.5% = 1/8, 16.67% = 1/6, 20% = 1/5, 25% = 1/4, 33.33% = 1/3, 37.5% = 3/8, 50% = 1/2, 62.5% = 5/8, 66.67% = 2/3, 75% = 3/4. Converting percentages to fractions makes calculations faster. For example: 25% of 480 = 480/4 = 120. Memorizing these fractions is essential for quick Quantitative Aptitude calculations.
Percentage Increase = (Increase/Original Value) x 100. Percentage Decrease = (Decrease/Original Value) x 100. If price increases by x% then decreases by x%, net effect is a decrease of x squared/100 percent. For Successive Percentage Changes: if first change is a% and second is b%, overall change = a + b + (ab/100) percent. This formula is crucial for profit/loss and interest problems in competitive exams.
Population problems use percentage increase formula. If population is P and annual growth rate is r%, then after n years: Population = P x (1 + r/100)^n. Example: Town population 50,000 grows at 10% per year. After 2 years = 50000 x 1.1 x 1.1 = 60,500. If growth rate decreases, use (1-r/100). These problems appear in SSC CGL, IBPS, and banking exams.
Shortcut methods: 1) For 1%: divide by 100, 2) For 10%: divide by 10, 3) For 5%: divide by 20 (half of 10%), 4) For 15%: find 10% then add half, 5) For 20%: divide by 5, 6) For 25%: divide by 4, 7) For 50%: divide by 2, 8) For 75%: multiply by 3 and divide by 4. Combine these for complex percentages: 35% = 30% + 5% = (3 x 10%) + (5%). Practice mental math with these shortcuts for exam speed.
Percentage = (part ÷ total) × 100
The answer is 382.0. Using Original value = final value ÷ (1 + rate), 458.4 ÷ 1.2 = 382.
The answer is 386.0. Using Original value = final value ÷ (1 − rate), 308.8 ÷ 0.8 = 386.
The answer is 59.15. Using Required value = percentage × quantity ÷ 100, 35 × 169 ÷ 100 = 59.15.
The answer is 136.8. Using Required value = percentage × quantity ÷ 100, 30 × 456 ÷ 100 = 136.8.
The answer is 139.65. Using Required value = percentage × quantity ÷ 100, 35 × 399 ÷ 100 = 139.65.
The answer is 112.25. Using Required value = percentage × quantity ÷ 100, 25 × 449 ÷ 100 = 112.25.
The answer is 42.3. Using Required value = percentage × quantity ÷ 100, 10 × 423 ÷ 100 = 42.3.
The answer is 271.0. Using Original value = final value ÷ (1 + rate), 311.65 ÷ 1.15 = 271.
