If 500 is the multiple of 100 that is closest to x and 400 is the multiple of 100 that is closest to y, which multiple of 100 is closest to x + y?

(1) x < 500

(2) y < 400

I found the wording in this Q to be really confusing.....wondering if anyone could decode it?

This is a range problem. Here's my take:

X has to be between 450 < x <= 550 (If x was below 450, then it will be closer to 400, and not 500.)
Similarly, 350 < y <=450. (Similar reasoning, as above.)

(1): 450 < x < 500, without knowing y (x+y)'s range cannot be determined. Insuff.
(2): 350 < y < 400, without knowing x (x+y)'s range cannot be determined. Insuff.

Combined: 800 < X + y < 900. We cannot determine if 800 or 900 is the closest multiple. Hence, E

What's OA?
