I would say answer E.

Given:

450<x<550
350<y<450

Stmt 1: limits x to be 450<x<500. Thus values of x+y can range betwee 800<x+y<950...obviously not enough since the closest multiple can be either 800 or 900.
Stmt2: limits y to be 350<y<400. Thus values of x+y will be in the range 800<x+y<950...not enough

Stmt 1 + Stmt 2
450<x<500
350<y<400

800<x+y<900
Again not enough, since the multiple can be either 800 (ex. x+y= 845) or 900 (ex. x+y=895) ...
Do you have an official answer?

You are right...OA is E but how did you take 450<x<550
350<y<450

also i really didnt understand what the ques is saying.... pls explain that ..thanks a lot

Multiples of 100 - 100, 200, 300, 400,500....etc You have a number X and it is said that 500 is a closest multiple of 100 to X. Consider example x=470...the closest multiple of 100 to x is 500. X= 535=> closest multiple of 100 to x is still 500. if x=560 => closest multiple of 100 to x is 600...hope it helps...

Closest to x+y
Given 500 is closest to x and 400 is closest to y
Range of x 451-549 Range of y (351-449)
Stmt1
X<500 so range of x is 451-499, Range of y (351-449)
Then range x+y =802 -948
Here the closest multiple of 100 can be both 800 and 900. So stmt1 alone is not sufficient
Stmt2
y<400 so Range of y is 351-399, range of x is 451-549,
Then range x+y =802 -948
Here the closest multiple of 100 can be both 800 and 900. So stmt2 alone is not sufficient
Comining both
X<500 so range of x is 451-499
y<400 so Range of y is 351-399
Then range x+y is 802-898
Here the closest multiple of 100 can be both 800 and 900
Hence both the stmts together are not enough
Please correct if I’m wrong
