The marked prices of a shirt and a trouser are in the ratio 1:2. The shopkeeper gives a 40% discount on the shirt. If the total discount on the shirt and trouser is 30%, then the discount offered on the trouser is

1. 15%
2. 20%
3. 25%
4. 30%

Correct answer: 25%

Solution

The total discount is a weighted average of the individual discounts based on marked prices. With shirt and trouser prices in the ratio 1:2, the shirt discount is 40% and the overall discount is 30%, so the trouser discount must be 25%.
