Question

S.P. of 6 bananas is the same as the C.P. of 5 bananas. Find the gain or loss per cent. ​

Answer 1

Cost price of 5 bananas = Selling price of 6 bananas

So,

$CP \: of \: 1 \: banana = \frac{1}{5}$

$SP \: of \: 1 \: banana = \frac{1}{6}$

As, CP of 5 bananas = SP of 6 bananas.There will be a loss.

$loss\% = \frac{( \frac{1}{5} - \frac{1}{6)} \times 100 } { \frac{1}{5} }$

$= \frac{ \frac{1}{30} \times 100 }{ \frac{1}{5} }$

$= \frac{100}{30} \times \frac{5}{1} = \frac{50}{3}$

$loss= 16 \frac{2}{3} \%$
