Let the present age of father and son be 7x and x years respectively. 

After 4 yr, 

age of father = (7x+4) yr 

age of son = (x+4) yr 

=> 7x + 4 = 4x + 16 

=> 3x = 12 

=> x = 4 

Therefore, 7x+x = 28+4 = 32 yr

Given: Ratio of present age of father and son = 7:1; Ratio after 4 years = 4:1

Let the present age of father and son be 7x and x respectively.

After 4 years, their ages will be (7x + 4) and (x + 4) respectively.

According to the given ratio, we have:

(7x + 4)/(x + 4) = 4/1

Solving the above equation, we get:

x = 4

So, present age of father = 7x = 28 and present age of son = x = 4

Therefore, sum of present age of father and son = 28 + 4 = 32 years.

Hence, option (d) 32 years is the correct answer.
