After getting two successive discounts, a shirt with a list price of ` 150 is available at ` 105. If the second discount is 12.5%, find the first discount.
Answer
Answer (as printed):
Explanation
Let the first discount be x%. Then, 87.5% of (100 – x)% of 150 = 105 $\Rightarrow \frac{87.5}{100} \times \frac{(100-x)}{100} \times 150 = 105 \Rightarrow (100 - x) = \frac{105 \times 100 \times 100}{150 \times 87.5} = 80 \Rightarrow x = (100 - 80) = 20$. First discount = 20%.
