Question

an article is sold for 300 at a profit of 20% find the cost price​

Answer 1

Answer:

$sp \: of \: article \: = 300 \\ profit\% = 20\% \\ cp = x \\ gain = \frac{20}{100} \times x \\ = \frac{2x}{10} \\ sp = cp + gain \\ 300 = x + \frac{2x}{10} \\ 300 = \frac{10x \: + 2x}{10} \\ 300 = \frac{12x}{10} \\ 12x = 300 \times 10 \\ x = \frac{300 \: \times 10}{12} \\ x = 250 \\ hence \: the \: cost \: price \: is \: 250$
