  • Question
  • Nitin's age was equal to square of some number last year and the following year it would be cube of a number. If again Nitin's age has to be equal to the cube of some number, then for how long he will have to wait?


  • Options
  • A. 10 years
  • B. 38 years
  • C. 39 years
  • D. 64 years

  • Correct Answer
  • 38 years 

    Explanation
    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.
