Numerical Aptitude (Chapter : Profit and Loss)
Cost Price
The price at which an article is purchased, is called the cost price or CP.
Selling Price
The price at which an article is sold, is called the selling price or SP.
Formulae
Gain or Profit = SP – CP
Gain per cent or Profit per cent = (Gain/CP x 100) or (Profit/CP x 100)
SP = (100+Profit%) x CP
100
Similarly, Loss = CP – SP Loss per cent =(Loss/CP x 100) ; SP =(100-Loss%)x CP 100
-
The Profit and Loss per cent is always calculated on the cost price.
-
If a trader professes to sell his goods at CP but uses false weight, then Gain per cent or Profit per cent =( Error x 100)% True Value-Error
Marked Price or List Price
Price that is indicated or marked on the article is called marked price or MP.
Discount
It is reduction given on the Marked Price or List Price of an article.
d per cent = 100 x discount; Selling Price = (100-d%)x MP MP 100 If a trade gets x% profit and x% loss in selling two different articles, then in over all transaction, there is always a loss which is given by
Loss % = (x/10)2
Example 1: What is the equivalent discount of three consecutive discount 30%, 20% and 5%?
Solution. Let MP = Rs 100
therefore, SP = 95% of 80% of 70% of 100 = (95/100) x (80/100) x (70/100) x 100 =
Rs 53.20
therefore, Required equivalent discount = Rs (100 – 53.20) = Rs 46.80
