Let the cost price of combined flour be Rs. X per kg
If the seller sold it on the actual price without obtaining any gain then,
Price of combined flour will be = X
Price of 5kg wheat = 5 * 12 = Rs. 60
Price of 15kg barley = 15 * 8 = Rs. 120
According to question, 5 kg of wheat is mixed with 15 kg of barley to make combined flour
5 * 12 + 15 * 8 = (5 + 15) * X
X = Rs. 9 per kg
Price of combined flour if the seller wants to sell it at 10% profit
Selling price of combined flour = 9 + 10% of 9 = 9 + 0.9 = Rs. 9.9 per kg
Hence, c is the correct answer.
