A fruit seller buys lemons at 2 for a rupee and sells them at 5 for three rupees. His profit percent is · ABC26GN2667

Suppose number of lemons bought = L.C.M. of 2 and 5 = 10. $$\begin{aligned} & \text { C.P. of } 10 \text { lemons }=₹\left(\frac{1}{2} \times 10\right)=₹ 5 . \\ & \text { S.P. of } 10 \text { lemons }=₹\left(\frac{3}{5} \times 10\right)=₹ 6 . \\ & \therefore \text { Profit } \%=\left(\frac{1}{5} \times 100\right) \%=20 \% \text {. } \end{aligned}$$
