Answer :
The average number of callers in the call centre is 112.5.
Number of callers received by the call centre per minute = 25
Average time each person spends on hold = 1 minute
Average time each caller spends talking = 3.5 minutes
The total amount of time of spending by each caller in the call centre is,
= Time spend on hold + Time spend on talking
= 1 + 3.5
= 4.5 minutes
The total amount of time spent by each caller in the call centre is 4.5 minutes.
The average number of callers in the call centre is,
= Total time spent in the call centre × Number of callers per minute
= 4.5 × 25
= 112.5
Therefore, the average number of callers in the call centre is 112.5.
