Correct Answer - Option 4 : 20 years

Let Shruti's age is ‘x’ years.

So, Raman’s age = 2x years

Age of Raman ten years ago was (2x – 10) years and that of Shruti was (x – 10) years.

According to question:

2x – 10 = 3(x – 10)

=> 2x – 10 = 3x – 30

=> 2x – 3x = -30 + 10

=> -x = - 20

=> x = 20

So, present age of Shruti is 20 years.

Hence, ‘**20 years**’ is the correct answer.
