Answer 2

Answer:

Option(2)

Explanation;

Let the present age of Sohan = x.

Let the present age of Sachin = y.

Given that Sohan is 20 years more than the present age of Sachin.

x = y + 20  ---------- (1).

Given that 3 years hence, it will be thrice that of Sachin.

x + 3 = 3(y + 3)

y + 20 + 3 = 3y + 9

y + 23 = 3y + 9

23 = 3y + 9 - y

23 = 2y + 9

23 - 9 = 2y

14 = 2y

y = 14/2

y = 7.


Substitute y = 7 in (1), we get

x = y + 20

x = 7 + 20

x = 27.


Therefore the age of Sohan = 27 years.


Hope this helps!
