Question

(a) The present age of a father is 4 years more than treble the age of his son. If the father was 35 years old before five years, find the present ages of father and his son. ​

Answer 1

33

Let the present age of father is x years and son is y years

Then according to the question

x−3y=3.............(i)

After 3 years

(x+3)−2(y+3)=10

x+3−2y−6=10

x−2y=13...........(ii)

Subtracting eq(i)and eq(ii)

y=10

Putting y=10 in eq(i)

x−3×10=3

x=33

Hence Father present age is 33 years.
