Answer: 54.6
Step-by-step explanation:
<span>Answer is C.
Explanation :-
Take the 1st case where Number of student(n) = 3 and Cost per student(c) is 24, we get n*c = 72
Take the 2nd case n = 6 and c =12, we get n*c = 72
Take the 3rd case n = 9 and c = 8, we get n*c = 72
By above observation we can say that product of Number of student and cost per student is 72 always.
Now for n = 12 we have to calculate c
n*c = 72
c = 72/12 = 6.
hence answer is option C.</span>
