Question

Four years ago, Sneha's age was one-third of the age, she will be in 6 years. How old is she now?
1. 9 years
2. 6 years
3. 8 years
4. 13 years

Answer 1

Correct Answer - Option 1 : 9 years

Let the present age of Sneha be 'a' years.

According to question:

a - 4 = 1/3 (a + 6)

⇒ 3 (a - 4) = a + 6

⇒ 3a - 12 = a + 6

⇒ 3a - a = 6 + 12

⇒ 2a = 18

⇒ a = 18/2

⇒ a = 9

So, Sneha is 9 years old now.

Hence, ‘9 years’ is the correct answer.
