Answer:
Time Needed In Minutes
Simple Claim 36
Complex Claims 75 (1.25 hour*60 Min)
Productive hours = 7.5 hrs. (In Minutes)
= 7.5 hours*60 min
= 450 minutes
Number of Working days = 20. Total Number of Productive Minutes in Month per person = 20 days * 450 minutes = 9000 minutes
Total Claims Processed Time Needed Total Time
Simple Claim 3000 36 108000
Complex Claims 960 75 72000
Total 180000
a. Number of Workers needed = Total Time Needed / Productive time put by single worker = 180,000 / 9000 = 20 workers
b. Number of Workers 23
Standard 20
Variance, Number of Workers = 23 - 20
Variance, Number of Workers = 3
Variance, Dollar Amount = Number of Workers * $135 * 20 days
Variance, Dollar Amount = $8,100
