MDCAT Logical Reasoning QUESTION #4434

Question 1

How many trees are in the orchard? Which of the statements below are needed to sufficiently answer this question? I. Ibrahim is a farmer and looks after half of the trees in the orchard. II. $300$ trees in the orchard are under Ibrahim's care.

I is enough
II is enough
Both I and II are needed✔️
Neither I nor II are sufficient

Correct Answer Explanation

Statement I alone tells us Ibrahim looks after half the trees but gives no actual number. Statement II alone tells us $300$ trees are under Ibrahim's care but does not tell us what fraction that is. Together: if Ibrahim cares for half the trees and that equals $300$, then total trees $= 300 \times 2 = 600$. Both statements are needed.
