Answer 2

Answer:

The present age of Sanjay is 45 years

Step-by-step explanation:

Given ratio of present ages of Ravi and Sanjay is 2:3.

Let age of Ravi be 2x

and age of Sanjay be 3x.

After 15 year age of Ravj will become =$(2x + 15) \: years$

After 15 years age of Sanjay will become

$(3x + 15) \: years$

After 15 years Ratio of their ages

$= \frac{(2x + 15)}{(3x + 15)}$

According to question,

$\frac{(2x + 15)}{(3x + 15)} = \frac{3}{4}$

By cross multiplication,

$4 \times (2x + 15) = 3 \times (3x + 15)$

$8x+60=9x+45 \\ 9x-8x=60-45 \\ x=15$

So present age of Ravi is (2x 15)= 30 years

and present age of Sanjay is (3x15)=45 years.
