Answer» Correct Answer - Option 3 : 12 years

Given:

Take my age 4 years hence, multiply it by 3 and then subtract 4 times my age three years ago

Calculation:

Let the age of the person be x years

According to the question,

⇒ x = 3(x + 4) – 4(x – 3)

⇒ x = 3x + 12 – 4x + 12

⇒ 2x = 24

⇒ x = 12 years

∴ The age of the person was 12 years.
