Profit and Loss Important Mathematics Formulas

Theory:


Cost Price (CP):    The money paid by the shopkeeper to the manufacturer or whole – seller to buy goods is called the cost price (cp) of the goods purchased by the shopkeeper.

Selling Price (SP): The price at which the shopkeeper sells the goods is called selling price (sp) of the goods sold by the shopkeeper to the customer.

Profit:                      If the selling price of an article is more than its cost price, then the dealer (or shopkeeper) makes a profit (or gain).

                                           i.e., Profit = SP – CP; SP > CP

Loss:                       If the selling price of an article is less than its cost price, the dealer suffers a loss.


                                          i.e., Loss = CP –SP; CP > SP

Some important formulae:
     

  •               Profit = SP – CP
  •             Loss = CP – SP
  •                 Profit percentage = (Profit/CP)x 100
  •                 Loss percentage =  (Loss/CP)x 100
  •                S.P =  [(100 + Profit%)x CP]/100
                                   OR

                    [(100 – Loss%) x CP]/100

  •           C.P = (100 x SP)/ (100 + Profit%)
                                    OR

                   (100 x SP)/ (100 – Loss%)
  •           SP  = (100 + x)% of CP; when Profit = x% of CP
  •                   SP =  (100 – x)% of CP; when Loss = x% of CP
                         


Some other related Formulae:
  •              Marked Price = CP + markup
  •            Marked price = CP + (%marked x CP)/ 100
  •               Selling price = Marked price – Discount
  •          Selling price = MP - (%discount x MP)/ 100 
Things to remember:

  • If two items are sold at the same price, one with a profit of x% and another with a loss of x%, there will be an overall loss given by x2/100.
  • If the CP of two items is the same, and one is sold at x% gain, other at x % loss, then the net loss or net profit=0.
  • On an offer to buy “a” goods and get “b” goods free, i.e., if “a+b” articles are sold at the rate of “a” articles, then the percentage discount = [(b/(a+b))×100]
  • If there are successive discounts of x% and y%, the effective discount can be calculated as [x+y – (xy/100) ]%
  • There are many shopkeepers who cheat by using false weights, then the gain to the shopkeeper on using the false weight can be calculated as follows (100 + Gain%)/100=(True Weight)/(False Weight).
