Explanation / Answer
1.
loan applications per month (R) = 750
applications in the Initial Review sub-process (IR) = 100
Applications in sub process A (IA) = 50
Applications in sub process B (IB) = 42
average flow time of an application = (IR+IA+IB)/R
= (100+50+42)/750
= 192/750
= 0.256 month
Number of days = 30*0.256 = 7.68 = 7.7 days
Option D, 7.7 days per application
2.
18% applications go to Sub process A = 18%*750 = 135
42% go to Sub process B = 42%*750 = 315
Hence total 42+18 = 60% go forward and rest 40% rejected = 750*40% = 300 applications
75% from Sub process A accepted and rest 25% rejected = 25%*135 = 33.75 applications
25% from Sub process A accepted and rest 75% rejected = 75%*315 = 236.25 applications
total rejected applications = 300 + 33.75 + 236.25 = 570 applications
option A 570 applications
3. average application at IR = 100
total applciations received per month = 750
average time taken in IR stage = 100/750 = 0.1333 months
in days = 0.1333*30 = 3.999 days = 4 days
option B, 4 days
4.
average application at IA = 50
total applciations received per month by sub process A = 18%*750 = 135
average time taken in IA stage = 50/135 = 0.3704 months
in days = 0.3704*30 = 11.11 days
Option C, 11.1 days
5.
average application at IB = 42
total applciations received per month by sub process A = 42%*750 = 315
average time taken in IA stage = 42/315 = 0.1333 months
in days = 0.1333*30 = 3.999 = 4 days
Option C, 4 Days
