Approximately two or three question in every bank exam or in other Government job exam such as SSC CGL exam surly comes from this topic of Profit and Loss. So learn these shortcut tricks to solve the maths problem in just few seconds. Here is the first one Shortcut for Profit and Loss Method.
SHORTCUT (1): To find out the selling price in any item in any given question we have to use the following shortcut formula:
Selling Price (sp) = (100 + (gain/loss)) /100 * Cost Price (CP)
Now by using the above formula we can solve any maths problem related to profit and loss within few second. Lest see some example related to this formula:
Example (1): A person bought a bicycle for Rs 250. For how much should he sell it so as to gain 10% profit on it?
Solution: In this problem we have to find out the selling price for which the person will get the 10% profit. So by using the Maths Shortcut (1) we have:
Selling Price (SP) = (100 + 10)/100 * 250
= 275 (So selling price should be this one to gain the 10% profit on it)
Example (2): A shopkeeper purchased a Book for Rs 560. For how much he should sell it so he gets 10% loss on it.
Solution: Again by using the Maths Shortcut (1). But in this we have to find out the selling price so that loss occur so we have to use subtraction as shown below in the solution.
Selling Price = (100 – 10) / 100* 560
