Show answer & explanation

Correct answer: A

Explanation

   The correct answer is option 1 i.e. 15

Understanding

Application

Marked price = Rs. 1000

Selling price = Rs. 680

So,

Total discount

= [(1000 – 680)/1000] × 100

= 32%

Two successive discounts of 20% and x% are offered on its marked price.

So,

32 = 20 + x – 20x/100

0.8x = 12

x = 15
