Chemtronics., a manufacturer of electronics equipment, has about 28,000 items in its inventory and has hired Lisa Ling to manage its inventory. Lisa has determined that 10% of the items in inventory are A items, 30% are B items, and 60% are C items. She would like to set up a system in which all A items are counted every 40 working days, all B items are counted every 80 working days, and all C items are counted every 120 working days. How many items need to be counted each day?
Total items are 28000 (Given)
10 % items are A items
Total A items = 0.1 * 28000 = 2800
30% items are B items
Total B items = 0.3 * 28000 = 8400
60 % items are C items
Total C items = 16800
A items should be counted every 40 days
Thus total A items counted each day = = = 70
Similarly ,Total B items counted each day = = 105
Total C items counted each day = = 140
Thus total items counted daily = 70 + 105 + 140 = 315
Thus 315 items need to be counted daily
