What is the difference between the maximum and minimum possible values of the cash disbursal done by the school?

To get the maximum possible values of the cash disbursal, let's assume that no student passed in both tests. Thus, the total no. of students passed at least one test = 60 + 33 = 93
So, the maximum possible values of the cash disbursal = $93k;
To get the minimum possible values of the cash disbursal, let's assume that the total no. of students who passed the chemistry test passed the math test. Thus, the total no. of students passed at least one test = 60
So, the maximum possible values of the cash disbursal = $60k
Thus, the difference between the maximum and minimum possible values of the cash disbursal = 93k – 60k = $33k
The correct answer:
B
Hope this helps!
