60 men --> 40 days
so they do work in a day is --> 1/40 parts
1 men(1 day) --> 1/(60*40)
so totally they have to do 1200 parts of work
For I five days 5(1/40)+
Next five days 5(55/2400)..... +5(40/2400)+....5(5/2400)=7/8
similarly they do for 60 days for the next 5 days no one will be there to complete the work.
So the job is incomplete and its answer cant be determined.
Incomplete task..

total no. of days will be 145 days

as in first 55 days the work done will be= [5/2400(60+55+....+5)]=325/400
and after 55 days the 5 men will continue working to finish the work for [(1-(325/400))*2400/5]= 90 days
so total days is 90+55= 145 days
