Question

a father is four times as old as his son now if 5 year later the father age will be 3 times of his son what is their age​

Answer 1

I can't solve the sum

But I can give you a hint

Let the father's age be 'x'

And the son's age be'y'

Now five years the father is 3 times the son means

(x+5)=3(y+5)

x+5=3y+15

x-3y-10=0

I think you can solve ahead

Hope it's helpful
