(1) p + 5q is positive.
(2) p + 4q is negative.
1. is not sufficient
2. is not sufficient either

Combining

p+5q is +ve and p+4q is negative => q is positive and p is -ve

p is not greater than q

Sufficient C

(1) p + 5q is positive.
(2) p + 4q is negative.
St.1) p + 5q is positive. --> p + 5q >0 --> p>-5q not suff
St.2) p + 4q is negative. --> p + 4q < 0 --> p<-4q not suff
combined ) -5q<p<-4q so q must be +ve and p must be -ve and hence p < q ...suff. AnsC
