Q1. A shopkeeper gives successive rebates of 20% and 10% on the printed price of a chair. If the price of the chair is ₹ 2,000, how much will the customer pay?
A 1,400
B 1,500
C 1,600
D 1,440 Correct
Explanation
Successive discounts are applied one after another, not simply added. On ₹ 2,000, a 20% rebate leaves 80% of the price, which is ₹ 1,600. A further 10% rebate on ₹ 1,600 leaves 90% of that amount, or ₹ 1,440. The values 1,400 and 1,500 would come from incorrect or unsupported discount handling, and 1,600 is only the price after the first rebate. Therefore the amount payable by the customer is 1,440.
