The marked price of a computer is Rs. 14000. Selling price of the computer is Rs. 9702. If two successive discounts of 23 percent and y percent are given, then what is the value of y?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 10%.
The marked price of a computer = Rs 14000
Selling price of the computer = Rs 9702
If two successive discounts of 23 percent and y percent are given
Marked price × (100 - first discount)/100 × (100 - second discount)/100 = Selling price
14000 × (100 - 23)/100 × (100 - y)/100 = 9702
⇒ 14 × 77 × (100 - y)/10 = 9702
⇒ 77 × (100 - y) = 6930
⇒ (100 - y) = 90
⇒ y = 100 - 90 = 10%
