    Clearly, we have to first find two numbers whose difference is 2 and of which the smaller one is a perfect square and the bigger one a perfect cube.Such numbers are 25 and 27.Thus, Nitin is now 26 years old. Since the next perfect cube after 27 is 64,so required time period = (64 - 26) years = 38 years.
