  • Question
  • A man buys a watch for Rs. 1950 in cash and sells it for Rs. 2200 at a credit of 1 year. If the rate of interest is 10% per annum, the man:


  • Options
  • A. gains Rs. 55
  • B. gains Rs. 50
  • C. loses Rs. 30
  • D. gains Rs. 30

  • Correct Answer
  • gains Rs. 50 

    Explanation

    S.P. = P.W. of Rs. 2200 due 1 year hence
    = Rs. [ 2200 x 100 ]
    100 + (10 x 1)
    = Rs. 2000.

    ∴ Gain = Rs. (2000 - 1950) = Rs. 50.
