A very gripping one :!: :wink:
from the stem statement, we can conclude that x>=450 ( because if x, for example, = 449---> the multiple of 100 that is closest to x is 400), similarly we can conclude that y>=350
---> x+y>=800

Is OA E? ...if correct, I'll explain further.

From the question, we can notice ;

451 <= x <= 550
351 <= y <= 450
---------------
802 <= x+y <= 1000

( statement 1) x < 500

451 <= x < 500
351 <= y <= 450
---------------------
802 <= x+y < 950

( statement 2) y < 400

451 <= x <= 550
351 <= y < 400
---------------------
802 <= x+y < 950

So my guess is D.

btw, just a small comment:
I think x is not nescessarily >=451 ....it can be>= 450.00000000000000000........1 coz the stem statement doesn't say that x is an integer :wink: . Similar to y.. A little change doesn't do harm to the whole reasoning process anyway :roll:

True, true.
Deep insight!

If we want to get 51, it's very important not to take for granted that those numbers are integers.

I think it is E.

x € (450,550)
y € (350,450)

(1) x € (450,500)
y € (350,450)
x+y € (800,950) Closest multiple of 100: 800 or 900

(2) x € (450,550)
y € (350,400)
x+y € (800,950) Closest multiple of 100: 800 or 900

(1)+(2) Same thing.

gamjatang nailed it. I think D has got to be the answer.

Doesnt "802 <= x+y < 950" mean that either 800 or 900 could be the closest multiple to x+y? Ie each one on their own is insufficient.

Here is my attempt:

450 =< x < 550
350 =< y < 450

--
800 =< y+x < 1000


St 1: x < 500

450 =< x < 500
350 =< y < 450

800 =< y+x < 950 -insuff - closest multiple is either 900 or 800

St 2: y < 400

450 =< x < 550
350 =< y < 400

800 =< y+x < 950 insuff - closest multiple is either 900 or 800

St. 1 + 2 together

450 =< x < 500
350 =< y < 400
800 =< y+x < 900 insuff - closest multiple is either 900 or 800

so I would say E.
