Answer 2

Solution :-

Let in x years Sarita will be 4 times as old as her son.

After x years Sarita will be (43 + x) years old and her son will be (7 + x) years old.

Then according to the question .

4(7 + x) = 43 + x

⇒ 28 + 4x = 43 + x

⇒ 4x - x = 43 - 28

⇒ 3x = 15

⇒ x = 15/3

⇒ x = 5

So, after 5 years, Sarita will be 4 times as old as her son.
