Question

Amita gave birth to twins when she was thirty years old. After x yr, the sum of the ages of Arnita and her children is 60 yr. What is the value of x?

Options

• 11 yr

• 10 yr

• 12 yr

• 9 yr

Answer 1

10 yr
Explanation:
Given the present age of Amita = 30 yr 
After x yr sum of the ages of twins
= (x + x) yr = 2x
Now, (30+ x) + 2x = 60
⇒ 3x = 60 - 30 = 30
⇒ x = 10 yr
