Answer 2

Answer:

Given the ratio of present age of father and son is 4:1.

Let their present age is 4x and x.

Then 4 years ago their age was 4x−4 and x−4.

Then according to the problem,

x−4

4x−4

=

2

11

or, 8x−8=11x−44

or, 3x=36

or, x=12.

So present age of father and son is 48 years and 12 years respectively.
