After getting two successive discounts, a shirt with a list price of Rs. 150 is available at Rs. 105. If the second discount is 12.5 percent, find the first discount.
A15%
B20% ✓ Correct
C25%
D17%
Correct answer: (B) 20% — The answer is 20 percent.
Explanation
★The answer is 20 percent.
★The list price 150 becomes 105 after two discounts.
★After the second discount of 12.5 percent, the price is 0.875 of the price after the first.
★So the price after the first discount is 105 divided by 0.875, which is 120.
★That is a fall from 150 to 120, a first discount of 30 on 150, which is 20 percent.
★So the first discount is 20 percent.
★So the answer is 20 percent.
