Question

Hitesh is 40 years old and Rohit is 60 years old. How many years ago was the ratio of their ages 3 : 5?

• A. $5$ years
• B. $10$ years
• C. $20$ years
• D. $37$ years

Answer 1

The correct option is B $10$ years

Given that,

The present age of Hitesh is $40$ year

And the present age of Rohit is $60$ year

Let $x$ year ago the ratio of their ages is $3:5$

Therefore,

$\frac{40-x}{60-x}=\frac{3}{5}$

$200-5x=180-3x$

$2x=20$

$x=10$

Hence, this is the answer.
