It is found that in a telephone system 60 subscribers initiate calls d...
Given:
- Number of subscribers = 60
- Duration of calls = 100 minutes

To find:
- Load in erlangs

Formula:
Load (in erlangs) = Total duration of calls / Time interval in minutes

Calculation:
Load (in erlangs) = 100 minutes / 30 minutes
Load (in erlangs) = 3.333 erlangs

Therefore, the correct answer is option C, 3.333 erlangs.

Explanation:
The load in a telephone system is a measure of the traffic or demand on the system. It is typically measured in erlangs, which represents the amount of traffic that a system can handle.

In this scenario, we are given that 60 subscribers initiate calls during a 30-minute interval and the total duration of all the calls is 100 minutes.

To calculate the load in erlangs, we need to divide the total duration of calls by the time interval. In this case, the load is equal to 100 minutes divided by 30 minutes, which gives us 3.333 erlangs.

This means that the telephone system is experiencing a load of 3.333 erlangs, indicating that there is a significant amount of traffic or demand on the system.
