Suppose the employees are allowed to process multiple order at a time, but the preference would be to finish orders of clients who placed their orders earlier. At what time is the order placed by Client 2 completely served?
Explanation:
Suppose Anish will complete preparation of the burger of client 1 by 10:10. In the meantime, Bani will complete the order of ice-cream of client 1 by 10:02. 3 portions of fries would have been prepared by 10:05.
At 10:05 when 2nd client's order comes, Bani would be free and the fryer would also be free. Bani can put the 2 portions of fries in the fryer (completes at 10:10) and start the order of 1 ice-cream of client 2 which will be completed by by 10.07.
So the entire order of client 2 will complete by 10:10.
Hence, option (a).
