Question

A MAN IS 3 TIMES AS OLD AS IS SON AFTER15 YEARS HE WILL BE TWICE AS OLD AS HIS SON FIND THEIR PRESENT AGES​

Answer 1

Let the age of son = x.

Then the age of man will be 3 times as old as his son = 3x.

After 15 years:

Age of son = x + 15.

Age of man = 3x + 15.

Given that Man will be only twice as old as his son.

3x + 15 = 2(x + 15)

3x + 15 = 2x + 30

3x = 2x + 15

x = 15.

Therefore the age of son = 15 years.

the age of man = 45 years.

Hope this helps!
