Question

A man bought bananas at the rate of 10 for Rs.15 and sold at the rate of one dozen bananas for Rs.15.Find his gain or loss per cent.

Answer 1

solution:-

here,

C.P. of 10 bananas= Rs 15

therefore, C.P. of 1 banana= 15/10

= 1.5 Rs

now,

one dozen = 12 bananas

so, S.P. of 12 bananas= Rs 15

therefore, S.P. of 1 banana= 15/12

= 1.25 Rs

clearly, S.P< C.P

this means, it is a loss for the shopkeeper.

now,

loss= (C.P.- S.P.)

= (1.50 - 1.25) Rs

= 0.25 Rs

now, loss percentage = (loss/C.P) multiplied by 100

= (0.25/1.50) * 100 (here, *= multiply)

= 16.66 % (answer)
