Bananas are bought at the rate of 6 for Rs. 5 and sold at the rate of 5 for Rs. 6. Profit per cent is

A) 36%

B) 42%

C) 44%

D) 48%

Correct Answer: C

Solution :

[c] LCM of 5 and \[6=30\]

\[\therefore \] 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% \[=\,\,\,\frac{\frac{11}{30}}{\frac{5}{6}}\times 100=\frac{11}{30}\times \frac{6}{5}\times 100=44\]%
