Consider a bank counter with two employees serving the customers. Deposit takes 5 minutes, cash withdraw takes 6 minutes, and electronic transfer takes 10 minutes. On average, there are 10 deposit transactions, 5 withdraw transactions, and 1 electronic transfer transactions in an hour. What is the utilization of the counter

75%

Explanation:

As we know that

Utilization of the counter is

= Required time ÷ Capacity in terms of minutes per hour

where,

Required time is

= 5 minutes × 10 deposit  transactions + 6 minutes ×  5 withdraw transactions + 10 minutes × 1 electronic transfer

= 50 minutes + 30 minutes + 10 minutes

= 90 minutes

And, the capacity is

= 60 × 2

= 120 minutes

So, the utilization is

= 90 minutes ÷ 120 minutes

= 75%
