Question:

Sanchi's age after 15 years will be 4 times her age 6 years back. What is the present age of Sanchi ?

Options:

15 years

12 years

13 years

8 years

Correct Answer:

13 years

Explanation:

Let the present age of Sanchi = a years

Sanchi's age after 15 years = a + 15

Sanchi's age 6 years ago = a - 6

ATQ,

(a + 15) = 4 × (a - 6)

3a = 24 + 15

a = 13

So Present age of Sanchi = 13 years.
