Profit and loss problems play a major role in quantitative aptitude test. It is bit difficult to score marks in competitive exams without knowing the shortcuts related to time and distance. We might have already learned this topic in our lower classes.Even though we have been already taught this topic in our lower classes, we need to learn some more short cuts which are being used to solve the problems in the above topic.
The only thing we have to do is, we need to apply the appropriate short cut and solve the problems in a limited time. This limited time will be one minute or less than one minute in most of the competitive exams.
Points to Remember
COST PRICE (C.P):
The amount paid or expenditure incurred in purchasing or producing an object is known as its cost price |
SELLING PRICE (C.P):
The price it which a person a product is called selling price. |
MARKED PRICE or LIST PRICE (M.P):
It is the price marked on the product or indicated in the price list. It is the price at which the product is intended to be sold. It is the price which is above the cost price and increased value on the cost price is called markup. |
PROFIT = S.P - C.P
PROFIT PERCENTAGE = (Profit/C.P)X100% |
LOSS = C.P - S.P
LOSS PERCENTAGE = (Loss/C.P)X100% |
MARGINAL PRICE = Cost Price + Markup value
SELLING PRICE = Marked Price - Discount |
DISCOUNT = Marginal price - Selling price
DISCOUNT PERCENTAGE = (Discount value/M.P)X100% |
Let "x" be the C.P of a product and "P" be the profit percentage
Then S.P = (100+P)% of C.P |
Let "x" be the C.P of a product and "P" be the loss percentage
Then S.P = (100-P)% of C.P |
SHOP KEEPER USING FALSE WEIGHT:
A trader cheats his customer to make a profit by stating that he sells at cost price.But he gives his customer less than 1000 grams (false weight) for every kg. Cheated Value = Original Weight - False Weight Profit Percentage = (Cheated Value/False Weight)X100% |
When two articles are sold at the same price such that there is a profit of P% on one article and a loss of P% on the other.Then irrespective of what the actual selling price is, the net result of the transaction is loss.
The loss percentage = P^{2}/100 |
When the cost price of two articles is same such that there is a profit of P% on one article and a loss of P% on the other.Then irrespective of what the actual selling price is, the net result of the transaction is no profit no loss. |
