Question

If the selling price of an article is 4/3 of its cost price, find the gain per cent?​

Answer 1

$let \: the \: CP \:be\: x \\ then, SP = \frac{4}{3} \times x \\ SP = \frac{4x}{3} \\ profit = SP - CP \\ Profit = \frac{4x}{3} - x => Profit = \frac{x}{3}$

$profit \% = \frac{profit}{cp} \times 100 \\ profit\% = \frac{ \frac{x}{3} }{x} \times 100 = \frac{100}{3} = 33.34\%$
