By selling 36 m of jute, a shopkeeper gains an amount equal to the selling price of 12 m of jute. Find the gain percentage.

Options
a) 50%
b) 40%
c) 45%
d) 55%

Solutions

As per questions
$SP \times 36M = CP \times 36M+SP \times 12M$
$\frac {SP}{CP} = \frac {36}{24}$
SP = 3
CP = 2
P = SP – CP
P = 3 – 2
P = 1
P% = $\frac12 \times100$
P% = 50%

Ans: a) 50%
