The rat between the invigilator and the examination candidates is 1:30 determine the number of invigilators for 2,5 examination conditions
Since the ratio of invigilators to examination candidates is 1:30, for 2 examination conditions there will be:
2 invigilators (1 + 1)
60 examination candidates (30 x 2)
For 2 examination conditions, there will be 2 invigilators.
For 5 examination conditions:
5 invigilators (1 + 1 + 1 + 1 + 1)
150 examination candidates (30 x 5)
Therefore, for 5 examination conditions, there will be 5 invigilators.
