A mixture of 12 kg of wheat flour costing Rs.16 per kg and 4 kg of corn flour costing Rs. 2 per kg is sold at Rs.16 per kg. What is the profit made in selling 40 kg of the mixture ?
The cost price of the mixture per kg =Â $$\ \frac{\ 12\times\ 16+4\times\ 2}{12+4}$$
= Rs. 12.5
Selling price of the mixture per kg = Rs 16
Profit made on selling 1 kg of mixture = 16-12.5=Rs. 3.5
Profit made o selling 40 kg of mixture = 40*3.5=Rs. 140
A is the correct answer.
