Question

1. Amir, who is two-thirds of his sister, Manisha's

age, is 10 years of age. Find Manisha's age.​

Answer 1

Manisha age = 15 years

Explanation:

Let

Manisha age = x

Amir = 2/3 of Manisha age

Amir = 10 years

Amir:

2/3 of x = 10

2/3 * x = 10

2/3x = 10

x = 10 ÷ 2/3

= 10 × 3/2

= (10*3)/2

= 30/2

= 15

x = 15 years

Therefore,

Manisha age = 15 years
