  1. 20%
  2. 15%
  3. 25%
  4. 18%
Show answer

Answer: A. Let CP of 1 article = 1. CP of 12 = 12 = SP of 10, so SP of 1 = 1.2. Profit % = (1.2-1)/1 × 100 = 20%.

Sample Medium question 6

A shopkeeper uses a false weight of 900 g instead of 1 kg but sells at the marked cost price. Find his profit percentage.

  3. 15%
  4. 10%

Sample Hard question 7

By selling 45 lemons for Rs. 40, a man loses 20%. How many lemons should he sell for Rs. 24 to gain 20%?

  1. 15
  2. 18
  3. 16
  4. 20
Show answer

Answer: B. Cost of 45 lemons = 40/0.8 = 50, cost per lemon = 10/9. For a 20% gain on Rs. 24, cost needed = 24/1.2 = 20, so lemons = 20 ÷ (10/9) = 18.

Sample Hard question 8

A retailer buys a radio for Rs. 225 and sells it at a loss equal to what he would have gained by selling it for Rs. 320. Find the cost price he actually paid relative to a selling price giving no profit no loss.

  2. 280
  3. 272.50
  4. 277.50
Show answer

Answer: C. If loss at Rs. 225 equals gain at Rs. 320, the no-profit-no-loss price is the average: (225+320)/2 = 272.50.
