Question

The price of a washing machine was decreased by 20% to £640.

What was the price before the decrease?

Answer 1

£800

Explanation:

Find 1% of the washing machine price using the percentage and the price of the washing machine after it decreased to help you.

100 - 20 = 80

80% = 640

1% = 640 ÷ 80 = 8

Now, since they asked the price before it decreased, they are asking for the full price.

100% = 8 x 100 = 800
