Question

The age of the father is three times the age of the son. If the age of the son is 15 years old, then the age of the father is:

​

Answer 1

Step-by-step explanation:

let the son age be x

father's age = 3x

After 15 years

son's age = x+15

Father's age = 3x+15

3x+15=2 (x+15)

3x+15=2x+30

x= 15 son's age now

father age = 3x= 15×3=45

Father's age now = 45 years

Hope it helps :)
