How old will the son be three years from now?
~~~~~~~~~~~~~~~~~~~~~~~


<pre>
Since Three years back the father was 24 years older than his son,

at present we have the same difference: today the father is 24 years older than his son.


So, two statements are valid simultaneously:

    (1)  today the father is 24 years older than his son,

and

    (2)  At present, the father is 5 times as old as the son.


Let the son age is x years; then the father is 5x years old, and

    5x - x = 24.


So, 4x = 24,  x = 24/4 = 6 years,  so the son is 6 years old now and the father is 6+24 = 30 years old now.


In 3 years from now, the son will be  6 + 3 = 9 years old.    <U>ANSWER</U>
