If x and y are non-zero integers and |x| + |y| = 32, what is xy?
(1) -4x - 12y = 0
(2) |x| - |y| = 16
(1) -4x - 12y = 0
(2) |x| - |y| = 16
Hi,
Cool Q. Thanks.
Stmt 1:
x+3y = 0
x = -3y
(x,y) is either (-24,8) or (24,-8). In both the cases, xy is a constant number. Hence, [spoiler]Sufficient.
[/spoiler]Stmt 2:
(x,y) is either (24,8) or (24,-8) or (-24,8) or (-24,-8). xy leads to two numbers amongst these four possibilities. Hence, Insuff
Guess it is A. Pls highlight if this is right / wrong.
Thanks.
