Re: Is p > q? (1) p + 5q is positive. (2) p + 4q is negative [#permalink]
IMO, OA is C

Stat 1
either p or q can be negative

Stat 2
either p or q can be negative

Stat 1 and Stat 2 together
tells that q>p
let p be -25 and q be 6
p+5q = -25+5(6) =-25+30 =6
p+4q = -25+4(6) =-25+24 =-1

Hence C

Yezz, you are missing something. I dont think B is sufficient, because all it tell us is that p+4q is negative.

Taking examples...

CASE 1 p>q. p=3, q=-1, then p+4q = 3-4 = -1.
CASE 2 p<q. p=-20, q=-1, then p+4q = -20-4 = -24

So (2) is INSUFF. Hence B cannot be the answer

(1) p + 5q is positive. ie: p+5q>0
(2) p + 4q is negative.ie: p+4q<0

P>-5Q......INSUFF

P<-4Q IE: P>4Q THUS SURELY P>Q ( wrong)

p<-4q ie: -p>4q...........insuff

together .........suff

B
( wrong answer)

C is the right answer to me as well.

i did a famous silly KG level mistake and did not change signs when i flipped the inequality
