To find the value of integer Y
Statement 1:
X is an integer such that X*Y = 6
X can be 1,2,3,6,-1,-2,-3,-6 implying that Y can be 6,3,2,1,-6,-3,-2,-1 respectively (Not sufficient)
Statement 2:
Y - X = 5
Y = X+5
Y can have infinite number of values depending on X (Not sufficient)
Combining statements 1 and 2 together
From statement 1 we have X,Y pairs as (1,6), (2,3), (3,2), (6,1), (-1,-6), (-2,-3), (-3,-2), (-6,-1)
Among the above pairs, (1,6) and (-6,-1) satisfy both the statements.
Hence statement together not sufficient to arrive at unique value of integer Y
Hence option E
