Let me try with a solution (plz correct me if I'm wrong):
We have the ratio equation as below :
A-only + E-only + Both = 1
1. For every 7A, we have 3E
=> there are 4 who take A only
=> A-only ratio is 4/7
we dont know about E-only & Both ratio. Insufficient.
2."For every three students taking at least one of the two courses, there is one student who takes up both"
=> In another word, for every 3 students at the insitute, there is 1 who takes both.
=> Both ratio is 1/3
Insufficient.
(1+2) : we deduce that
E-only = 1 - 4/7 - 1/3
So C is the answer
