C Correct answer
Explanation

Total cost = (50 * 7) + (20 * 8) = 350 + 160 = 510. Total weight = 70 kg. Total revenue = 70 * 10 = 700. Profit = 700 - 510 = 190.

AI explanation

The total cost for the 50 kg of wheat bought at Rs. 7 per kg is Rs. 350, and the cost for the 20 kg bought at Rs. 8 per kg is Rs. 160. The overall cost price for the 70 kg mixture is 350 + 160 = Rs. 510. The shopkeeper sells all 70 kg at Rs. 10 per kg for a total selling price of Rs. 700, yielding a total profit of 700 - 510 = Rs. 190. The total profit is Rs. 190.
