Question

A vendor bought lemons at the rate of $6$ for a rupee. How many for a rupee must he sell to gain $20\%$?

• A. $4$ lemons
• B. $5$ lemons
• C. $6$ lemons
• D. No lemons

Answer 1

Answer: (B)

$5$ lemons

C.P. of $6$ lemons $=\text{Rs.}1$ , Gain $=20\%$
$\therefore$ S.P. of $6$ lemons $=\frac{120}{100}=\text{Rs.}1.20$

$\text{Rs.}1.20$ is the S.P. of $6$ lemons.

$\therefore$ $\text{Rs.}1$ is the S.P. of $\frac{6}{1.2}=5$ lemons
