(a) On the basis of the times observed through four cycles, determine the normal time for the
job.
(b) Calculate the standard time if there is a fatigue allowance of 15 % and a contingency
allowance of 10%.
(c) If a worker is employed on a 5 day, 37.5 hour/week with 1.5 hours per day for breaks, how
many workers are needed for a daily production of 1500?
