A can do a piece of work in 10 days, B in 15 days. They work together for 5 days, the rest of the work is finished by C in two more days. If they get Rs. 3000 as wages for the whole work, what are the daily wages of A, B and C respectively (in Rs):

Correct Answer: 300, 200, 250

Explanation:

A's 5 days work = 50%  


B's 5 days work = 33.33% 


C's 2 days work = 16.66%     [100- (50+33.33)] 


Ratio of contribution of work of A, B and C =  50   :   33 1 3   :   16 2 3  = 3 : 2 : 1   


A's total share = Rs. 1500 


B's total share = Rs. 1000 


C's total share = Rs. 500  


 


A's one day's earning = Rs.300  


B's one day's earning = Rs.200  


C's one day's earning = Rs.250
