Concept

Prior to the manufacturer's or provider's profit being added, the cost price is the whole amount spent on the production of goods or services. Actual cost, average cost, and latest cost are some other names for it. Profit and loss are always calculated using the item's cost price and its selling price.

The following is the formula for calculating gain (profit) % using selling price:

Formula for cost price: 100/(100 + Profit%) SP.

Given

A a man earns a profit of 10% while selling an article for A.

Find

we are asked to find out the cost price of that article.

Solution

from the given data, we know that:

Selling price of article = A

and profit = 10%

therefore, Cost price = 100×sp/100₊profit%

Cp = 100×A/100₊10

Cp = 100A/110

Cp = 10A/11

hence we got the cost price of the article as 10A/11
