Question

A party of 5 goes to the Green Iguana. The waiter takes 10 seconds to get from the kitchen to the table (or vice versa), and takes 30 seconds to manually take each person's order at the table. The waiter always starts in the kitchen, goes out to a table, takes the order for the batch (whatever the batch size), and then delivers the order for only that batch back to kitchen. If the waiter takes the table's orders in batches of 1 (only taking the order of 1 person), what is the waiter's total time required to process the job for the entire table?

1. 250 seconds

2. 170 seconds

3. 10 seconds

4. 30 seconds

Explanation / Answer

The waiter takes 10 seconds to get to kitchen and 10 seconds to get from kitchen to tables. Hence the setup time will be 20 seconds for each batch. The pure processing time for each person is given to be 30 sec.

Now total time for each party will be = 20 (setup) + 30(processing) = 50 seconds.

Hence, for party of 5 total time will be 5 * 50 = 250 seconds.

Therefore, the correct option is 1. 250 sec
