AI explanation

The ratio of the wages of A and B will be equal to the ratio of their one day's work, which is 1/20 : 1/30 or 3:2. Let the ratio of the work done by B and C be 2:x, so the difference in their shares is Rs. 1500 for a total wage of Rs. 9000. Assuming the earnings of C corresponds to the remaining amount, the ratio of efficiency of A, B and C is 3:2:1. The share of A is 3/(3+2+1) of Rs. 9000, which equals Rs. 4500.
