A mobile is listed at ₹ 20,000 and a discount of 25% is offered on the list price. What addition discount must be offered to the customer to bring the net price to ₹ 13,200 ?

  • A.10%
  • B.12%
  • C.32%
  • D.18%

Answer: B

The additional discount is 12%.

After the 25% discount, the price is \(20000 \times 0.75 = 15000\). The further reduction needed is \(15000 - 13200 = 1800\), and as a percentage of the already discounted price:

\[ \frac{1800}{15000} \times 100 = 12\% \]

Successive discounts are taken on the reduced price, not the list price. 10% would leave the price at 13,500 and 18% at 12,300, and 32% treats the whole fall from 20,000 as a single further discount.
