Question

.A dress has a thirty percent discount applied and is on sale for 63 pound. What was the original price of the dress before the reduction?

Answer 1

The original price of the dress before the reduction was 90 pound.

Explanation:

This question can be solved using a rule of three. The current price, which is 63 pound, is 100 - 30 = 70% = 0.7.

The original price is x pound, and is 100% = 1. So

x pound - 1

63 pound - 0.7

`0.7x = 63`

`x = (63)/(0.7)`

`x = 90`

The original price of the dress before the reduction was 90 pound.
