X, Y, Z are positive integers, and X+Y=190. Is X>Z?
1). Z=95
X+Y = 190,
If X = 100, y = 90, Z = 95. i.e. X>Z
If X = 90, y = 100, Z = 95. i.. X<Z.
Insufficent to answer the question
2). X*Y=9000
X = 100, y = 90, or
X = 90, y = 100,
Since the value of Z is not provided, this statement is insufficent to answer the question
From 1 and 2
If X = 100, y = 90, Z = 95. i.e. X>Z
If X = 90, y = 100, Z = 95. i.. X<Z.
Insufficent to answer the question
