Question 1132324
.
<pre>
Let x be the Dheeraj age.


Then the father's age is 2x years, while the mother's age is 2x-4 years.


4 years ago Dheeraj's age was x-4 years, while the mother's age was (2x-4)-4 = 2x - 8 years.


The condition says


2*(x-4) = 2x - 8.


This equation is, actually, an <U>IDENTITY</U>: it is true for <U>ANY</U> value of x,  and, therefore, 

the value of x <U>CAN NOT be determined uniquely</U> from the equation.


<U>ANSWER</U>.  The age of Dheeraj can be <U>any positive number</U>,  and <U>CAN NOT BE DETERMINED uniquely</U> from the given condition.
