Answer::
i. We are told that the current age of the Father is 36 years but the current age of the son should be 'X'
ii. Lets assume the age of the Father when the son was born was (36-X)which is also the current age of the son. From (i) above we are told the current age of the son is "X" which MUST BE EQUAL to the age of the Father when his son was born
iii. Let's then have (36-X)=(X)Solve for X, Which you get ((X=18))
Since we have said X is the current Son's age, then 5 yrs ago the son was X-5=18-5=13 years
Therefore, five years ago the age of the Son was 13 Years old.
