Data Sufficiency

If -2x>3y, is x negative?
1. y>0
2. 2x+5y-20=0

This is very interesting question.

Statement I
y> 0, therefore x<0. Sufficient.

Statement II
2x+5y-20=0
2x+5y = 20

2x+3y + 2y = 20

since we know that 3y+2x < 0
therefore y has to be greater than 0, thus, x<0.

Sufficient.

Hence D.


The second statement from the look of it is insufficient, but when start to solve it you'll find out that x has to be negative.

Thanks buddy.
It can't get simpler than that!
Thanks a lot!!!
