  • Question
  • If x and y are the two digits of the number 653xy such that this number is divisible by 80, then x+y is equal to ?


  • Options
  • A. 5
  • B. 4
  • C. 3
  • D. 2

  • Correct Answer


  • Explanation

    Since 653xy is divisible by 5 as well as 2, so y = 0.
    Now, 653x0 must be divisible by 8.
    So, 3x0 must be divisible by 8. This happens when x = 2
    x + y = (2 + 0) = 2.
