Question

The price of an item is marked as 150. What
will be its selling price (in) after successive
discounts of 25%, 20% and 10%?​

Answer 1

Answer:

After getting 2 successive discounts, a shirt with a list price of Rs 150 is available at Rs 105. If the second discount is 12.5%, find the first discount?

Solution: Let the two discounts be x% and 12.5%.

150(1-x)(1–0.125) = 105, or

(1-x)*0.875 = 105/150 = 0.7

1-x = 0.7/0.875 = 0.8, or

x = 1–0.8 = 0.2 or 20%.

The first discount was 20%. Answer.

Check: 150*0.8*0.875 = 105. Correct.
