Question

five years ago i was thrise as old as my son and ten years later i shall be twice as old as my son. How old are we now

Answer 1

5 years ago means - 5
let take the age of son as x
so five years ago = x-5
and age of 'I' as 3x-5

10 years later
son age = x-5+10= x+5
'I' age = 2(3x-5)

equation


x+5=2(3x-5)

Answer 2

Five years ago
Let son's age be x
My age is 3x

Ten years later
Son's age is x+10
My age is 2(3x)

So,
x+10 = 2(3x)
x+10 = 6x
10 = 6x-x
10 = 5x
x = 10/5
x = 2

Hence,
Son's age = 2 years
My age = 6 years
