Given T/S = 3/80
Now we got to find S, when T = 5.
Corresponding S = (80/3)*5 = 133.3
S cannot be a decimal, hence D

or 400 >3S and S<133.33, which is 133.

What's the doubt?
if the ratio must be larger than 3 / 80
And there are 5 TA's, then first:
3 / 80 = 5 / x
x = 400/3 = 133.3
So the ratio must be larger than 5 / 133.3
You can't have 0.3 students, so you can have 133 students and still have a larger ratio than 5 / 133.3
