40 years
After 5 years . if ages are F and S , then
F=3S where F = S+30
F= 3*(F-30) = 3F-90
2F = 90
F =45

so present age = 45-5= 40 years

A. 40yrs

Let Son's age: x
Father's age : x + 30

In 5 years:
Son's age: x + 5
Father's age: x + 35

In 5 years the father is thrice as old as his son so:
3(x + 5) = x + 35
x = 10

Current father's age = x + 30 -->That is 40.

A. 40yrs

Let Son's present age = x
then Father's present age = x + 30

after 5 years
Son's age = x + 5
Father's age = x + 35

As per condition given after 5 years the father will be thrice as old as the son so:
x + 35 = 3(x + 5) => 2x = 20
=> x = 10
So Son's present age = 10 years
and Father's prsent age = x + 30 = 10 + 30 = 40 years,
Hence Ans: A 40 years
