  • In a bangel shop, the shopkeeper displays the bangels in the form of a square, then he is left with 38 bangles with him. If he wants to increse the size of square by one unit each side of the square, he found that 25 bangles fall short of in completing the square.

  • Options
  • A. 1690
  • B. 999
  • C. 538
  • D. Cannot be determined

  • Correct Answer
  • 999 

    Explanation

    Let the number of bangles be x. Then, x - 38 is a perfect square and x + 25 is a perfect square.
    Now, using the option, we find that x = 999
    999 - 38 = 961 is a perfect square.
    999 + 25 = 1024 is a perfect square
