Nikita bought 30 kg of wheat at the rate of $ 9.50 per kg and 40 kg of wheat at the rate of $ 8.50 per kg and mixed them. She sold the mixture at the rate of $ 8.90 per kg. Her total profit or loss in the transaction was :
-
- $ 2 loss
- $ 2 profit
- $ 7 loss
- $ 7 profit
Correct Option: A
On the basis of given question ,
Total CP of 70 kg of wheat = $ (30 × 9.5 + 40 × 8.5) = $ (285 + 340) = $ 625
Total S.P. of 70 kg of wheat = $ (8.90 × 70) = $ 623
∴ Loss = Total CP of 70 kg of wheat - Total SP of 70 kg of wheat
Loss = $ (625 – 623) = $ 2
