It takes 6 technicians a total of 10 hours to build and program a new server from Direct Computer, with each working at the same rate. If six technicians start to build the server at 11:00 AM, and one technician per hour is added beginning at 5:00 PM, at what time will the server be complete?

Total # of units: 6 * 10 = 60 man hours

From 11:00 to 5:00 i.e. 6 hours, # of units completed = 6 * 6 = 36 man hours.

# of man hours left = 60-36 = 24.

From 5-6, 7 additional manhours are completed. 7 men at work.

Similarly 6:00-7:00, 8 additional manhours and 7:00-8:00 9 additional manhours.

i.e the rest 24 (7+8+9) manhours are completed by 8:00

Got the same

One person can complete 1/(6*10) amount of work in 1 hour
From 11 to 5 there are 6 hours so 6 people working will complete
6*6 * 1/60

After 5 each person is added after one hour

36/60 + 7/60 + 8/60 + 9/60 = 60/60 work is complete
5 o clock 6 o clock 7 o clock 8 o clock
