Answer 1

Answer:

profit % = 25%

Given:-

• selling price of 8 apples is equal to cost price of 10 apples

To find:-

• gain percent

solution:-

$let \: \: the \: \: cost \: price\: of \: 10 \: apple \\ and \: \: sellig. \: \: price \: \: of \: 8 \: apple \: be \: (x) \\ \\ there \: for \\ cost \: of \: each \: apple \: = \frac{x}{10} \\ \\ selling \: price \: \: of \: each \: apple = \frac{x}{8} \\ \\ \: now \: first \: we \: will \: find \: profit \\ as \: we \: all \: know \\ \\ profit = selling \: price \: \: - cost \: price \\ \\ profit = \frac{x}{8} - \frac{x}{10} \\ \\ \: cross \: \: muliply \: this \: \\ \\ profit = \frac{10 x- 8x}{80} \\ \\ profit = \frac{2x}{80} \: \\ \\ now \: for \: profit\% \\ \\ p\% = \frac{p}{c.p} \times 100 \\ \\ p\% = \frac{ \frac{2x}{80} }{ \frac{x}{10} } \times 100 \\ \\ p\% = \frac{2x}{80} \times \frac{10}{x} \times 100 \\ \\ profit\% = 25\%$

Answer 2

The gain percent​ = 25 %

Step-by-step explanation:

Given,

The cost price(CP) of 10 apples = The selling price(SP) of 8 apples

Let the cost price(CP) of 1 apple = Rs. 1

To find, the gain percent​ = ?

∴ The cost price(CP) of 10 apples = 10 × Rs. 1 = Rs. 10

The selling price(SP) of 8 apples=Rs.10

∴  Gain = 10 - 8 = Rs. 2

∴ Gain Percent (%) $=\dfrac{Gain}{CP} \times 100$

$=\dfrac{2}{8} \times 100$

$=\dfrac{100}{4}$

= 25 %

Thus, the gain percent​ = 25 %
