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 = (1)/(5)`

`SP \: of \: 1 \: banana = (1)/(6)`

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

`loss\% = \frac{( (1)/(5) - (1)/(6)) * 100 } { (1)/(5) }`

`= ( (1)/(30) * 100 )/( (1)/(5) )`

`= (100)/(30) * (5)/(1) = (50)/(3)`

`loss= 16 (2)/(3) \%`
