Question

Hamid has gained weight.

Answer 1

Is  = %
of     100

So 
 
88 = 110
 x      100

Cross multiply 

8800 = 110x
Divide both sides by 110

x= 80 kg

Answer 2

Answer:

Hamid's normal weight is 80 kg .

Step-by-step explanation:

Let us assume that the normal weight be x .

As given

Hamid has gained weight.

He now weighs 88kg, which is 10% higher than his normal weight.

10% is written in the decimal form

$= \frac{10}{100}$

= 0.10

10% increase in the weight = 0.10 × Normal weight.

                                             = 0.10 × x

                                             = 0.10x

Thus

Total weight of Hamid =  Normal weight + 10% increase in the weight

88 = x + 0.10x

88 = 1.10x

$x = \frac{88}{1.10}$

x = 80 kg

Therefore the Hamid's normal weight is 80 kg .
