Ram completed the work in = 10 hours.
Ajit completed the work in = 12 hours
Suresh completed the work in = 15 hours.
Total time taken = 10+12+15
= 37 hours.
Total work done is =60
Ram does 6 work in 1 hour, Ajit does 5 work in 1 hour, Suresh does 4 work in 1 hour.
Ram left 2 hours of the start and ajit left 3 hours after the completion.
So Ram leaves= 60-30= 30
So total time taken = 2+2+3= 7 hours.
