The Correct Option is C

Solution and Explanation

First, we calculate the average earnings per day in medium operations: - The total medium earnings are Rs. 636.53, Rs. 461.73, Rs. 79.10, Rs. 159.64, Rs. 89.70, Rs. 472.31, Rs. 735.22, Rs. 576.57, Rs. 286.48, Rs. 512.10, Rs. 1303.88, Rs. 1017.94, Rs. 46.56, Rs. 116.40, which sums to Rs. 6534.25.
- The average earnings in medium operation is Rs. 6534.25 / 15 = Rs. 436.95.
