PROFIT -:
if the cost price of an article is less than its selling price then the difference between the selling price and the cost price is known as profit
LET'S SEE FORMULA
[tex]profit \: = \: sp - \: cp \\ \\ sp = cp + \: profit \: \: \\ \\ profit \: \% = \frac{profit \: \times 100}{ \: cp \: } \\ \\ profit \: = \frac{cp \: \times \: profit \: \%}{100} \\ \\ cp \: = \frac{100 \times sp}{100 + profit\%} [/tex]
LOSS
if the selling price of an article is less than its cost price then the difference between cost price and selling price is known as loss
let's see formula
[tex]loss \: = cp - sp \\ \\ sp \: = \: cp \: - loss \: \\ \\ cp \: = loss \: + sp \\ \\ loss\% \: = \frac{loss \: \times 100}{cp} \\ \\ loss \: = \frac{ \cp \times loss\% }{100} \\ \\ sp = cp \times ( \frac{100 - loss }{100} )[/tex]
