Girish bought 100 kg of Rice for Rs. 1100 and sold it at a loss of as much money as he received for 20 kg rice. At what price did he sell the rice?
Explanation:
CP per kg = 1100/100 = Rs. 11.
Loss on 100 kg is equal to selling price of 20 kgs.
∴ 100 × (CP - SP) = 20 × SP
⇒ SP = 5/6 × CP = 5/6 × 11 = 9.167
Alternately,
The loss is covered by the sale of 20 extra kgs of rice i.e. CP of 100 kg = SP of 120 kg
∴ SP of 1 kg = CP of 100/120 kg = 100/120×11 = Rs. 9.1666
Hence, option (b).
