  1. A trader sells goods to a customer at a profit of k% over the cost price, besides it he cheats his customer by giving 880 g only instead of 1 kg. Thus his overall profit percentage is 25%. Find the value of k ?
    1. 8.33%
    2. 8.25%
    3. 10%
    4. 12.5%
  1. Correct Option: C

    Profit % = 25 / 100
    = 120 + k (profit) / 880 (sale)

    ∴ k = 100
    Therefore, net profit % = (100 / 1000) X 100 = 10%
