Correct Answer - Option 3 : 12 years and 14 years
Given:
Ankita is two years younger than Anu.
After four years Anu's age will be two times of Ankita's age three years ago
Calculation:
Let the age of Ankita be x
⇒ age of Anu will be = x+2
After four years Anu's age will be two times of Ankita's age three years ago.
⇒ (x + 2) + 4 = 2 (x – 3)
⇒ x + 6 = 2x – 6
⇒ x = 12
⇒ x + 2 = 12 + 2 = 14
∴ Age of Ankita is 12 years and age of Anu is 14 years.
