Answer 2

Sankar's present age is 28 years.

Explanation:

• We have given current age ratio of Rajesh and Sankar i.e. 4:7

• Let present ages of Rajesh and Sankar be 4x & 7x respectively.

• After four years the age of Rajesh and Sankar will be 4x+4 & 7x+4 respectively.

• After four years the ratio of their age is given to be 5:8

So, as per given condition we can write that

$\frac{4x+4}{7x+4} = \frac{5}{8}$

$32x+32 = 35x+20$

$3x=12$

$x = 4$

Therefore the present age of Rajesh is $4x = 4\times 4 = 16$ years and Sankar is $7x = 7\times 4 = 28$ years.

Hence, Sankar's present age is 28 years.
