Question

A grocer purchased 200 kg of rice at ₹25 per kg .he sold 80 kg of rice at the gain of 10 percent and 40 kg at the loss of 4 kg percent at what rate per kg should he sell the remainder to gain 8 percent on his total investment?

Answer 1

Answer:

Rs.28 per kg

Step-by-step explanation:

CP of 1 kg rice = Rs.25

CP of 200 kg = Rs.25 × 200 = Rs.5000

CP of 80 kg rice = Rs.2000

Gain = 10% = Rs.200

SP of 80 kg rice = Rs.2200

CP of 40 kg rice = Rs.1000

Loss = 4% = Rs.40

SP of 40 kg rice = Rs.960

Remaining rice = 80 kg

Gain in total investment = 8% = Rs.400

Hence, total SP = Rs.5400

Total money got = Rs.3160

Money to get = Rs.(5400 - 3160) = Rs.2240

Hence, SP of 80 kg rice = Rs.2240

SP of 1 kg rice = Rs.(2240 ÷ 80) = Rs.28
