Best answer
Correct Answer - Option 4 : 27 years

Given:

3 years from Alka's birthday, she will be twice as old as she was 12 years ago

Calculation:

Let Alka’s age today be x years. 

Then, Alka’ age after 3 year = (x + 3) years.

12 years ago, Alka's age = (x - 12) years

According to question:

⇒ x + 3 = 2 × (x - 12) 

⇒ x + 3 = 2x – 24

⇒ x = 27
