Question

A fruit seller buys lemons at $2$ for a rupee and sells them at $5$ for three rupees. What is his profit percentage?

• A. $15\%$
• B. $20\%$
• C. $10\%$
• D. $25\%$

Answer 1

The correct option is B

$20\%$

Given that a fruit seller buys lemons at $2$ for a rupee and sells them at $5$ for three rupees.

The cost price of one lemon, $CP$ $=Rs\frac{1}{2}=0.5$

The selling price of one lemon $SP$ $=Rs\frac{3}{5}=0.6$

Profit ($\%$)

$$\begin{gathered} =\frac{SP-CP}{CP}\times 100 \\ =\frac{0.6-0.5}{0.5}\times 100 \\ =0.2\times 100 \\ =20\% \end{gathered}$$

Therefore, the correct option is (b)
