A father is three times as old as his son. 15 years hence,he will be twice as old as his son.What is the sum of their present ages?​

Answer»

Step-by-step explanation:

LET his son age be x.

Age of father = 3x

After 15 YEARS son age = 15+ x

Father age = 15+3x

15+3x= 2x

3x-2x = 15

x =15

Therefore Father age is 45,son age is 15.
