CONCEPTUAL QUESTION


RULE OF INEQUALITY:
Cross multiplication of a variable is allowed only if the sign of variable is known because
1) If positive variable changes side during cross multiplication then the inequality sign remains the same
2) If Negative variable changes side during cross multiplication then the inequality sign FLIPS


Statement 1) a/b > 1

Case 1: a=2, b=1 and a>b
Case 2: a=-2, b=-1 and a<b

NOT SUFFICIENT

Statement 2) b/a < 1

Case 1: a=2, b=1 and a>b
Case 2: a=-2, b=-1 and a<b

NOT SUFFICIENT


Combining the two statements

Case 1: a=2, b=1 and a>b
Case 2: a=-2, b=-1 and a<b

NOT SUFFICIENT

Answer: Option E
