Question

The sum of the ages of a father and son is 52 years.Five years ago, the age of the father was five times the age of the son. Find their present age?

Answer 1

let their present ages be
father=f
son=s
then, f+s= 52.......(i)
5 years ago, father=f-5
son=s-5
given, f-5=5(s-5)
f-5=5s-25
5s-f=25+5
5s-f=20.............(ii)
after solving,
s=12
f=40

Answer 2

Answer:

Solution : Let the age of son = x years

And the age of father = 3x years

According to question

X + 3x = 52

4x = 52

X = 52/4

X =13
