A's income is 25% more than B's income. By what percent is B's income less than A's?
सही उत्तर: क) 20%
If B = 100, A = 125. B is less by 25/125 × 100 = 20%. The base changes to A's income, so the answer is not 25%.

The population of a town is 50,000 and grows at 10% per annum. What will it be after 2 years?
सही उत्तर: घ) 60,500
Population = 50,000 × (1.1)² = 60,500. Growth compounds, so 60,000 (simple 20% growth) is too low.

A salary is first increased by 20% and then decreased by 20%. What is the net effect?
सही उत्तर: ख) 4% decrease
Net factor = 1.20 × 0.80 = 0.96, which is a 4% decrease. Equal percentage rise and fall never cancel out; the result is always a loss of (x²/100)%.

The price of sugar rises by 25%. By what percent must a family reduce its consumption so that its expenditure on sugar stays the same?
सही उत्तर: घ) 20%
Required reduction = r/(100 + r) × 100 = 25/125 × 100 = 20%. It is not 25%, because the reduction is calculated on the new, higher price.

A number increased by 25% becomes 150. What is the original number?
सही उत्तर: क) 120
Original × 1.25 = 150, so original = 150 ÷ 1.25 = 120. Subtracting 25% of 150 (giving 112.5) is the common mistake, since the 25% is taken on the original number, not on 150.
