  • Question
  • A man has Rs.480 in the denominations of one-rupee notes, five-rupee notes and ten-rupee notes. The number of notes of each denomination is equal. What is the total number of notes that he has?


  • Options
  • A. 45
  • B. 60
  • C. 75
  • D. 90

  • Correct Answer
  • 90 

    Explanation
    Let number of notes of each denomination be x

    Then x + 5x + 10x = 480

    ⟹ 16x = 480

    x = 30.

    Hence, total number of notes = 3x = 90.
