Show answer & explanation

Correct answer: D

Explanation

 The correct answer is option 4 i.e. 8%

Understanding

Application

Marked price = Rs. 1500

And

Selling price = Rs. 1173

Hence,

Overall discount

= [(1500 – 1173)/1500] × 100

= 21.8%

First discount = 15%

Suppose 2nd discount = x%

So,

15 + x – 15x/100 = 21.8

85x/100 = 6.8

x = 8

Hence,

2nd discount = 8%
