Hi, I hope I am in the right forum. I came across this question while preparing for my GMAT exam. [Note : I am not good in maths since high school.] Appreciate if some1 can explain to me since I have left school 10 years ago.
This relates to Data Sufficiency (DS) problem:
e, d are Real Numbers. If e>d，is ed<0?
Statement 1: (e^2)d < e(d^2)
Statement 2 : e+d < 0
Are those Statements sufficient to answer the question: If e>d，is ed<0?
(A) Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
(B) Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
(C) BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
(D) EACH statement ALONE is sufficient.
(E) Statements (1) and (2) together are NOT sufficient.
Thank you in advance.
