he now weighs 88kg which is 10% higher than his normal weight
what is hamids normal weight

Answer 1

Let's say Hamid's normal weight is x.

88kg = 110%x

88kg=11/10x

Divide by 11 on each side

8kg=1/10x

Multiply by 10 on each side

80kg=x

Hamid's normal weight is 80kg

Answer 2

so begin to find out 10% of 88 which is 8.8 then subtract 8.8 from 88 to find your answer
