T wants to buy earphones worth ₹1,500 and shopkeeper agrees to sell it for ₹1,450. How much percent discount does the shopkeeper offer to T?

  • A.\(\frac{10}{3}\%\)
  • B.\(\frac{12}{5}\%\)
  • C.\(\frac{14}{5}\%\)
  • D.\(\frac{8}{3}\%\)

Answer: A

The discount is 10/3 per cent. The discount is 1500 - 1450 = 50 rupees, and as a percentage of the marked price \[ \frac{50}{1500} \times 100 = \frac{10}{3}\% \] which is 3 1/3 per cent.

12/5, 14/5 and 8/3 per cent would be discounts of 36, 42 and 40 rupees, not 50.
