Question

some toffees are bought at 6 for a Rupee and the same number at 4 for a rupee.If the whole lot is sold at 5 for a Rupee, find the gain or loss percent?​

Answer 1

CP of six toffees = Rs 1

CP of one toffee = Rs 1/6   ----- (1)

SP of 5 toffees = Rs 1

SP of 1 toffee = Rs 1/5          ---- (2)

Comparing (1) and (2)

Taking LCM = 30

1/6 and 1/5 become 5 and 6  in the numerator

Since CP (5) less than SP (6), we conclude that the transaction is profit.

Actual profit = 6-5 = 1

Profit percentage = profit X 100/CP

= 1 X 100/5 = 20%        

Ans: 20%

Answer 2

Rs. In other words, he must sell 5 toffees for a rupee to gain 20%

20÷5=4

loss%= 4
