Answer» Cost price of 10 kg of rice = Rs. 400 × 10 = Rs. 4000 Cost price of 5 kg of rice = Rs. 2000 and the cost price of the REMAINING 5 kg of rice = Rs. 2000 Also given that trader got 20% loss for half of the quantity We know that loss% = (CP - SP)/CP × 100 ⇒ 20 = (2000 - SP)/2000 × 100 ⇒ 200000 - 40000 = 100SP ⇒ SP = Rs. 1600 ∴ Loss for first half = 2000 - 1600 = Rs. 400 Also given that profit for SECOND half is 10% ⇒ 10 = (SP - 2000)/2000 × 100 ⇒ 100SP = 20000 + 200000 ⇒ SP = 2200 ∴ Profit for second half = 2200 - 2000 = Rs. 200 ∴ Net there is a loss of Rs. 200 Final loss % = (net loss/total cost price × 100) = 200/4000 × 100 = 5% |
