### CAT 2017 – Slot 1 – Logical Reasoning and Data Interpretation - Healthy Bites is a fast food joint serving three items: burgers, fries and ice cream

##### Healthy Bites is a fast food joint serving three items: burgers, fries and ice cream. It has two employees Anish and Bani who prepare the items ordered by the clients. Preparation time is 10 minutes for a burger and 2 minutes for an order of ice cream. An employee can prepare only one of these items at a time. The fries are prepared in an automatic fryer which can prepare up to 3 portions of fires at a time, and takes 5 minutes irrespective of the number of portions. The fryer does not need an employee to constantly attend to it, and we can ignore the time taken by an employee to start and stop the fryer; thus, an employee can be engaged in preparing other items while the frying is on. However fries cannot be prepared in anticipation of future orders. Healthy Bites wishes to serve the orders as early as possible. The individual items in any order are served as and when ready; however, the order is considered to be completely served only when all the items of that order are served. The table below gives the orders of three clients and the times at which they placed their oders; Assume that only one client's order can be processed at any given point of time. So, Anish or Bani cannot start preparing a new order while a previous order is being prepared.

Q. 1: At what time is the order placed by Client 1 completely served? A) 10:17 B) 10:10 C) 10:15 D) 10:20

##### Q. 2: Assume that only one client’s order can be processed at any given point of time. So, Anish or Bani cannot start preparing a new order while a previous order is being prepared.At what time is the order placed by Client 3 completely served?A) 10:35 B) 10:22 C) 10:25 D) 10:17

Q. 3: Suppose the employees are allowed to process multiple orders 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?
A) 10:10
B) 10:12 C) 10:15 D) 10:17

Q. 4: Suppose the employees are allowed to process multiple orders at a time, but the preference would be to finish orders of clients who placed their orders earlier.
Also assume that the fourth client came in only at 10:35. Between 10:00 and 10:30, for how many minutes is exactly one of the employees idle?
A) 7 B) 10 C) 15 D) 23

Explanation:- As the item which take the maximum time is burger, client 1 will be completely served by 10.00

+ 10 minutes = 10.10

Explanation:- The time taken for the different clients are Client 1 – 10.00 – 10.10 (burger)

Client 2 – 10.10 – 10.15 (fries)

Client 3 – 10.15 – 10.25 (burger)

Explanation:- When they are allowed to process multiple orders, the time taken would be

Client 1 – 10.00 – 10.10 (Anish)

Client 2 – 10.05 – 10.10 (Bani)

The second client can be served by 10.10

Explanation:- The time for which exactly one employee would be free would be

10.02 – 10.05 – (Bani) – 3 Minutes.

10.10 – 10.17 (Anish/Bani) – 7 minutes (depending on who prepares the order for client 3. After 10.17 both of them would be free.

∴ One of them would be free for 3 + 7 = 10 minutes.
