  • Question
  • Vinod have 20 rupees. He bought 1, 2, 5 rupee stamps. They are different in numbers by the reason of no change, the shop keeper gives 3 one rupee stamps. So how many stamps Vinod have ?


  • Options
  • A. 10
  • B. 18
  • C. 12
  • D. 15

  • Correct Answer
  • 10 

    Explanation

    Given total rupees = 20 Rs
    No. of one rupee stamps = 3
    Now, remaining money = Rs. 17
    With that he buys only 2 and 5 rupee stamps
    Let number of Rs. 5 stamps = K
    Let number of Rs. 2 stamps = L
    5K + 2L = 17
    K = 3, L = 1 (possible)
    L = 6, K = 1 (possible)
    => But given that they are different in number so, K is not equal to 3
    one rupee stamps = 3
    2 two stamps = 6
    5 rupee stamps = 1
    Total number of stamps = 10.
