The first four articles for this topic provide you the same. You the table of contents given below to go through these articles.

**1.** One can generate a profit only if Selling Price> Cost Price

**2.** One generates a loss when Selling Price < Cost Price.

**3.** Profit = Selling Price – Cost Price

%profit = {(Selling Price – Cost Price)/Cost Price} x 100

**4.** Loss = Cost Price – Selling Price

%Loss = {(Cost Price – Selling Price)/Cost Price} x 100

**5.** Sale price :- If there is a profit of P %,

Cost Price = C

Then SP = {(100+P)/100}xC

**6.** If there is a loss of L %,

Cost Price = C

Then

SP = {(100-L)/100}xC

**7.** Cost price :-

If there is a profit of P %,

Cost Price = C

Sale price= SP

Then C = {100/(100+p)} x SP

If there is a loss of L %,

Then

C = {100/(100-L)}xSP

**8. **A dishonest dealer claims to sell his goods at cost price ,but he uses a weight of lesser weight .Find his gain%.

**9.** A shopkeeper sells an item at a profit of x % and uses a weight which is y % less .find his total profit

**14.** A reduction of x% in price enables a person to buy y kg more for Rs. A. Then the

**15.** When there are two successive profits of x% and y% then the net percentage profit =[x+y+xy/100]

When there is a profit of x% and loss of y% then net percentage profit or loss = [x – y – xy/100]

**Note: If the final sign in the above expression is positive then there is net profit but if it is negative then there is net loss.**

**16.** A sells goods to B at a profit of x% andB sells it to C at a profit of y%. If C pays RsP for it,then the cost price for A is

Note:- for loss replace plus sign with minus .

17. When each of the two things is sold at the same price,and a profit of p% is made on the first and a loss of L% is made on the second,then the percentage gain or loss is .

18. If profit percentage and loss percentage are equal, put P=L

=> %loss = p^{2} /100
