Back to paper

After two successive discounts, a pen with a list price of ₹175 is available at ₹129.15. If first discount is 10%, what is the second discount?

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e. 18%

Price after 1st discount = 90% of 175

= Rs. 157.5

The second discount amount = 157.5 - 129.15

= Rs. 28.35

Let the required discount percentage be x

x% of 157.5 = 28.35

x = 28.35×100157.5\dfrac{28.35 × 100}{157.5}

x = 18

So the second discount is 18%
