Although from Option 1, the total no. of students studying French can be deduced but the total no. of students cant be deduced which is very important conclude on the comparison. Thus, A is ruled out.

From Option 2 also the total no. of students on the institute cannot be figured out.

Thus, B is ruled out.

Since, using both also we cannot find the total no. of students, E is the correct answer.

Hope it helps .. :)

uhm I think B could work

X = number of students who study French
Y = number of students who study Japanese

we know that 0.04X is the number of students who study French and Japanese
2 says that 0.1Y is the number of students who study Japanese and French so

0.04X = 0.1Y ---> X > Y
