A pair of shoes is listed at 800. After two successive discounts, it is sold for 612. If the first discount offered was 10%, what was the second discount percentage?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. 15%.
MP = 800
SP after first discount = 800 × 0.9 = 720
Let second discount = d%
720 × (1 – d/100) = 612
⇒ 1 – d/100 = 612/720 = 0.85
⇒ d/100 = 1 - 0.85 = 0.15
⇒ d = 15
So, the second discount is 15%.
