Question

The sum of the present ages of ram and his son is 85 years 5 years ago ram was twice as old as his son then find the present age of his son?

Answer 1

let the age of ram be x and age of his son be y
therefore, x+y=85 -------(1)
now, before 5 years
ram was twice as old as his son
then 2x-y=5 -------(2)
adding equation (1) and (2) we get
x+y=85
+ 2x-y=5
_______
3x=90
x=30
substituting value of x in eq. (1)
30+y=85
y=55
but son cannot be smaller than the father
therefore age of ram is 55 and age of his son is 30

Age of father is 55 years.
