Question

A bicycle was reduced by 20%. The reduced price was £100. What was the original price?

Answer 1

£125

Explanation:

Let the original price be x

Reduction = 20%

Price after reduction = (100 - 20)% = 80%

80% of x = £ 100

`(80)/(100)x = 100\\\\x=100*(100)/(80)\\\\`

x = 125

Original price = £125
