~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


<pre>
if father tell his son, "I was of your present age where you were born",

it means that the father age now is twice the son present age.


So, if the father is 36 years old now, then his son is 36/2 = 18 years old.


Hence, 5 years back the son was 18-5 = 13 years old.    <U>ANSWER</U>
