A company has a job to prepare certain number of cans and there are three machines A, B and C for this job. A can complete the job in 5 days, B can complete the job in 25 days and C can complete the job in 2 days. How many days the company will it take to complete the job if all the machines are used simultaneously?
Choose the correct choice.
A) 4 days B) 5/3 days C) 50/37 days D) 37/50 days E) 14 days
Let the total number of cans to be prepared be 50.   The number of cans prepared by A in 1 day = 10.   The number of cans prepared by B in 1 day = 2.   The number of cans prepared by C in 1 day = 25.   Thus, the total number of cans that can be prepared by all the machines working simultaneously in a single day = 37.   Therefore, the number of days taken to complete the whole work = 50/37 days.   ANSWER:50/37 days
