wording of questions

by ch0719 » Fri Jan 02, 2009 8:41 pm
I have encountered a supposedly easy question on MGMAT, however the wording puzzled me:

If -3x < 6, which of the following must be true?
A x < -3
B x < -2
C x > 3
D x > -2
E x > 0

this question can be easily solved by division on both sides, and result is
x>-2, which most people would incline to choose D

But the question asks which of the following MUST BE TRUE, so imo C,D, and E are all correct. Therefore I think this question's wording is flawed.

What do you guys think?

If x>-2 x >0 could be true and not must be true

If x>-2 x >3 could be true and not must be true


Since its a MUST BE TRUE question the only thing we can say for sure always is x>-2 hence D)

Consider -1 only D fits
