Q41
ArithmeticPercentage, Profit & Loss
20% loss on selling price is what percent loss on the cost price?
  1. a.25%
  2. b.15%
  3. c.$16\frac{2}{3}$%
  4. d.$16\frac{1}{3}$%

Answer: (C) $16\frac{2}{3}$%

Take the selling price as 100; the loss is 20, so the cost price is 120. Loss on cost price = 20 ÷ 120 × 100 = $16\frac{2}{3}$%. 25% is what a 20% gain on selling price would be on cost, a different situation.
