Important Tricks of Profit and Loss:

Cost Price (CP): The money paid by the shopkeeper to the manufacturer or money paid by the customer to the shopkeeper is called the price (CP) of the goods.

Selling Price (SP): The price at which the shopkeeper sells the goods is called the selling price.

Here, I am providing important short tricks so you can easily solve profit and loss questions.

Useful Tricks:

(1) If SP is greater than CP then we have profit, so formula of profit will be =

     SP>CP---- Profit

     Profit = SP-CP

(2) If SP is Less than CP then we have Loss, so formula of Loss will be =


    Loss = CP-SP

(3) Profit and Loss is always counted on CP


(4) To solve any question of profit and loss, you have to always assume 

CP = 100%

Q.1. A person incurs 5% loss by selling a watch for Rs. 1140. At what price should the watch be sold to earn 5% profit.

(A) 1320

(B) 1260

(C) 1210

(D) 1350

Ans .   B

Short Trick

CP = 100% {point no. 4, you have to always assume CP=100%)

If CP = 100% and Loss is 25% which mean SP= CP – L%

SP = 100% - 5% = 95%

So, we can say

SP = 95% = 1140

If CP=100% and Profit is 40% Which mean SP= CP+ Profit%

SP= 100%+5%=105%

So, we have to find value of 105% and 105% is equal to

= 1260.

So, New S.P = Rs. 1260.


Q.2. A Bought pens at the rate of 15 per rupee and sold them at the rate of 12 for a rupee. His gain percent is

(A) 25%

(B) 26%

Shor Tricks 

We are gating profit here, So

                                                              15  :  12

                                                                 5   :   4

The difference of 5 : 4 is 1

Profit and loss always counted CP , which means
