Work Rate of A = 100/10 = 10% per day.
Work rate of B = 100/15 = 6.66% per day.
Work Completed by A and B in 5 days = 5 * (10 + 6.66) = 83.33%.
So, A completed = 5 *10 = 50% work, thus will get 50% of 3000 = 1500.
Daily wage of A = 1500/5 = 300.
B completed = 5 * 6..66 = 33.33% work.
B get = 1000.
Daily wage of = 200.
C will get = 500.
Daily wage of C = 250.
