Question
Given that pqrs≠0, is pq2r3s4<0?
(1) pq2r3<0
(2) q2r3s4<0
(1) pq2r3<0
(2) q2r3s4<0
Answer: Option A
:
A
Option (a)
Statement (1) alone is sufficient, as "s” is raised to an even power and will not alter the state of the expression (positive or negative)
Statement (2) is not sufficient as we do not know anything about p, and p is raised to an odd power (1). Hence, the state of the expression (i.e. positive or negative) depends on "p"
