​

Answer 1

Answer:

$Selling \: \: Price : 249 \\ Gain \: \: \% = 10\% \\ \\ Cost \: \: Price = Selling \: \: Price \times \frac{100}{100 + 10} \\Cost \: \: Price = 249 \times \frac{10 \cancel 0}{11 \cancel 0} \\ Cost \: \: Price = \frac{2490}{11} \\ \boxed{ Cost \: \: Price = \underline{ \underline{ 226}}} \\ \\ Gain = Selling \: \: Price - Cost \: \: Price \\ Gain = 249 - 226 \\ \boxed{Gain = \underline{ \underline{23}}}$
