Answer 2

Step-by-step explanation:

Cost Price: The amount paid to purchase an article or the price at which an article is made is known as its cost price. The cost price is abbreviated as C.P.

Selling Price: The price at which an article is sold is known as its selling price. The selling price is abbreviated as S.P.

Profit

If the selling price (S.P.) of an article is greater than the cost price (C.P.), the difference between the selling price and cost price is called profit. Thus, if S.P. > C.P., then

Profit = S.P. – C.P.\\ S.P. = C.P. + Profit \\ C.P. = S.P. – Profit

Profit=S.P.–C.P.

S.P.=C.P.+Profit

C.P.=S.P.–Profit

The profit percent is the profit that would be obtained for a C.P. of Rs 100 i.e,

Profit\quad percent=\left( \frac { Profit }{ C.P. } \right) \times 100

Profitpercent=( profit/cp )×100
