Here Some Basic Formulas/Rules Are given below :-

Cost Price : The price at which an article is purchased, is called its cost price, abbreviated as C.P.
Selling Price : The price at which an article is sold, is called its selling price, abbreviated as S.P. 1
Profit or Gain : If S.P. is greater than CR, the seller is said to have a profit or gain.
Loss : If S.P. is less than C.P., the seller is said to have incurred a 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% = Gain X 100  
                   C.P.

  5. Loss% = Loss X 100  
                   C.P.

  6. S.P. = 100 + Gain%   X C.P.
                 100

  7. S.P. = 100 - Loss%   X C.P.
                 100

  8. C.P. =        100          X S.P.
             100 + Gain%

  9. C.P. =        100          X S.P.
             100 - Loss%

  10. If an article is sad at a gain of say, 35%, then S.P. = 135% of C.P.

  11. If an article is sold at a loss of say, 35%, then S.P. = 65% 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%/10 )2 = ( x/10 )2

  13. If a trader professes to sell his goods at cost price, but uses false weights, then
    Gain% =              Error             X 100 %
               (True Value) - (Error)
