<em>Answer:</em>
<em>Let the present ages of man and son be x and y respectively
</em>
<em>x+y = 45 </em>
<em>
</em>
<em>5 yrs ago , age of man = (x-5)
</em>
<em>age of son = (y-5) </em>
<em>(x-5)(y-5) = 4(x-5)
</em>
<em>(y-5) = [4(x-5)] / (x-5)
</em>
<em>y-5 = 4. [(x-5) got cancelled out]
</em>
<em>y = 9 yrs </em>
x+y = 45 yrs
x+9 = 45
x = 45-9 yrs => 36 yrs
