The ratio between the invigilator and the examination candidate is 1:30.determine the number of invigilator for 215 examination candidate
To determine the number of invigilators for 215 examination candidates, we need to set up the ratio:
1:30 = x:215
Cross multiply to solve for x:
1 * 215 = 30 * x
215 = 30x
Divide both sides by 30 to solve for x:
215/30 = x
x = 7.17
Since the number of invigilators must be a whole number, we round up to the nearest whole number:
Therefore, there would be 8 invigilators for 215 examination candidates.
