Answer:
Let the total work to be done be 30 unit.
Efficiency of A = 30/10 = 3 units/day
Efficiency of B = 30/15 = 2 units/day
Wa = 3*5 =15 units ; Wb = 2*5 = 10 units
Combined work done by A and B in 5 days = (3+2)*5 =25 units
Work left = 5 units (completed by C)
Their wages will be in the ratio of the work done by each
Wa : Wb : Wc = 15 : 10 : 5 = 3 : 2 : 1
Total wage of A = 1500*3/6 = Rs 750
Total wage of B = 1500*2/6 = Rs 500 i.e., per day wage = 500/5 = Rs 100
Total wage of C = 1500*1/6 = Rs 250 i.e., per day wage = 250/2 = Rs 125
So, combined daily wage of B and C = Rs (100+125) = Rs 225
