Ashish is younger than Parul by 10 years. If the ratio of their ages is 3:5, what are their ages?

Let the present age of Ashish be A years and that of Parul be P years.

According to the given statement, Ashish is younger than Parul by 10 years.

⇒ P = A + 10       ----(i)

It is also given that the ratio of their ages is 3:5.

⇒ $\frac{A}{P}$ = $\frac{3}{5}$

Using equation (i), we substitute P:

⇒ $\frac{A}{A + 10}$ = $\frac{3}{5}$

Cross-multiplying to solve for A:

⇒ 5A = 3(A + 10)

⇒ 5A = 3A + 30

⇒ 5A - 3A = 30

⇒ 2A = 30

⇒ A = 15

Now substituting the value of A back into equation (i):

⇒ P = 15 + 10

⇒ P = 25

Hence, the present age of Ashish is 15 years and Parul is 25 years.

Therefore, the correct answer is option 2: 25, 15
