A) 36%
B) 42%
C) 44%
D) 48%
Correct Answer: C
$ \therefore $ CP of 30 bananas $ =5\times 5=Rs.,25 $ and SP of 30 bananas $ =6\times 6=Rs.,36 $ Profit $ =Rs.(36-25)=Rs.11 $ So, profit percentage $ =\frac{11}{25}\times 100=44 $ % Alternate Method CP of 1 banana $ =Rs.\frac{5}{6} $ SP of 1 banana $ =Rs.\frac{6}{5} $ Profit $ =SP-CP=\frac{6}{5}-\frac{5}{6}=\frac{36-25}{30}=\frac{11}{30} $ Profit% $ =,\frac{\frac{11}{30}}{\frac{5}{6}}\times 100=\frac{11}{30}\times \frac{6}{5}\times 100=44 $ %
