i)Â Â Â Â Â Â Â 5 classes per week

5 hours per day

3 days

In each class 25 students

Number of hours = 5*3

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â =15 hours a week

Productivity = No of hours/ no of students

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 15/25= 0.6

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Or 60%

ii)Â Â Â Â Â 3 classes per week

3 hours per day

5 days

In each class 55 students

Number of hours = 3*5

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â =15 hours a week

Productivity = No of hours/ no of students

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 15/55= 0.273

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Or 27.3%

iii)Â Â Â 3 classes per week

5 hours per day

5 days

In each class 55 students

Number of hours = 5*5

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â =25 hours a week

Productivity = No of hours/ no of students

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 25/55= 0.455

It will decrease productivity from 60 % (current) to 45.5%, this is due to the increased number of students per class.
