I think there's an error on the answer choices.

4X + 5X = 9X
5X + 6X = 11X

X = 9.5

Then at least there should be 9 * 9.5 = 85.5 = 86 students at least initially.

Second statement: CD+DE = radius of larger circle; 2 (CD+DE)-DE = AD = diameter of smaller circle. So we have the radii of both circles again. Sufficient
