Answer 2

GIVEN

Father's age is three times the son's age.

And sum of their ages = 100

TO FIND

Son's age

SOLUTION

Let the son's age be x

Then, the father's age be 3x

Sum of their ages = 100

= 3x + x = 100

= 4x = 100

= x = 100 ÷ 4

= x = 25

NOW,

Son's age = x = 25

Fathers age = 3x = 3 × 25 = 75

PROVE

Sum of their ages = 100

25 + 75 = 100
