Question

On an average day 3% of your employees are absent from work.You need 215 employees to operate all the machines.What is the minimum number of employees you need in order to have enough employees to operate all the machines on an average day?

Answer 1

Let e be the minimum number of workers needed.

e(100-3)/100≥215

97e/100≥215

97e≥21500

e≥21500/97

e≥221.6

Since the number of employees must be an integer...

e≥222

So the minimum number of employees needed is 222.
