Question

A person sells a article for ₹550, gaining ${\frac{1}{10}}^{th}$ of its CP. Find the gain%

Answer 1

Given selling price of an article =Rs.$550$
Let the cost price be =Rs. x
Since, gain =${\frac{1}{10}}^{th}$ of C.P
$=\frac{x}{10}$ as C.P=x
Therefore, gain$\%$=$\frac{\frac{x}{10}}{C.P}\times 100$
=$\frac{\frac{x}{10}}{x}\times 100$
=$\frac{1}{10}\times 100$
=$10\%$
