Profit-loss

  1. Gain = (S.P.) – (C.P.)
  2. Loss = (C.P.) – (S.P.)
  3. Loss or gain is always reckoned on C.P.
  4. Gain Percentage: (Gain %)
        Gain % = Gain x 100
    C.P.
  5. Loss Percentage: (Loss %)
        Loss % = Loss x 100
    C.P.
  6. Selling Price: (S.P.)
        SP = (100 + Gain %) x C.P
    100
  7. Selling Price: (S.P.)
        SP = (100 – Loss %) x C.P.
    100
  8. Cost Price: (C.P.)
        C.P. = 100 x S.P.
    (100 + Gain %)
  9. Cost Price: (C.P.)
        C.P. = 100 x S.P.
    (100 – Loss %)
  10. If an article is sold at a gain of say 30%, then S.P. = 130% of C.P.
  11. If an article is sold at a loss of say, 30% then S.P. = 70% of C.P.
  12. When a person sells two similar items, one at a gain of say x%, and the other at a loss of x%, then the seller always incurs a loss given by:
        Loss % = Common Loss and Gain % 2 = x 2 .
    10 10
  13. If a trader professes to sell his goods at cost price, but uses false weights, then
        Gain % = Error x 100 %.
    (True Value) – (Error)
