Solutions

Expert Solution

Total no. of items = 7000; working days per month=19; per quarter=61; per half year=120

No. of A items = 11%=11%x7000=770; Frequency of count per half year=No. of working days per half year/Count of days after which item has to be counted=120/19=6.32; No. of counts for each item in half year=770*6.32=4866.4

No. of B items=37%=37%x7000=2590; Frequency of count per half year=No. of working days per half year/Count of days after which item has to be counted=120/61=1.97; No. of counts for each item in half year=2590*1.97=5095

No. of C items=52%=52%x7000=3640; Frequency of count per half year=No. of working days per half year/Count of days after which item has to be counted=120/120=1; No. of counts for each item in half year=3640*1=3640

Total count in half year=4866+5095+3640=13601; Total no. of items to be counted each day=13601/120=113items

The answer is 113 items
