Question

A trader mixes 26kg of rice at rs20 per kg with 30kg of rice of other variety at rs 36 per kg and sells the mixer at rs 30 per kg. Find his profit percent?

Answer 1

CP of 1st variety rice=20
CP of 2nd variety rice=36
CP of the 56 kg rice mixture=(26×20+30×36)=520+1080=1600
SP of the 1 kg rice mixture=30
SP of the 56 kg rice mixture=30×56=1680
Gain=SP−CP=1680−1600=80
Gain%=Gain/CP×100 =801/600×100 =100/20=5%

Answer 2

Price of 26 kg rice = ₹20 x 26 = ₹520
Price of 30 kg rice = ₹36 x 30 = ₹1080
Total Rice = 56 kg

Price of Rice = ₹1600
Selling price = 56 x 30 = ₹1680
Profit = 1680 - 1600 = ₹80
Profit percentage =
= 80/1600 x 100
= 5%
