Question

I am three times as old as my son. Five years later, I shall be two and a half times as old as my son. How old am I and how old is my son?

Answer 1

Answer:

Your present age is 45 and that of your son is 15.

Step-by-step explanation:

Let your current age is x and that of your son is y

∴x=3y      ·········(1)

After five years your age willl be x+5 and that of your son is y+5

∴(x+5)=2.5(y+5)     ·········(2)

By solving (1) and (2)

We get,

x=45 and  y=15

So your present age is 45 and that of your son is 15.
