Consider the following for the next ten (10) items that follow: Each item contains a Question followed by two Statements. Answer each item using the following instructions: Question : Is xy positive?
Statement Ix = ∛(−0.19683)
Statement IIy = ∛x
Elementary MathematicsNumber System
- AIf the Question can be answered by one of the Statements alone, but not by the other.
- BIf the Question can be answered by either Statement alone.
- CIf the Question can be answered by using both the Statements together, but cannot be answered by using either Statement alone.
- DIf the Question cannot be answered even by using both Statements together.
Explanation
Statement I gives x = ∛(−0.19683) < 0 but says nothing about y. Statement II gives y = ∛x but says nothing about x. Together, x < 0 forces y = ∛x < 0, so xy > 0 — the question is answered only by both statements jointly: option (c).
