1 alone is sufficient
Incorrect Answer2 alone is sufficient
Incorrect AnswerBoth 1 and 2 are not sufficient
Incorrect Answer1 and 2 together are sufficient
Correct AnswerExplanation:
Let’s analyze both the statements:
- Statement 1: R is shorter than P but taller than other friends.
- So, P > R > others (Q, S, T, U in some order).
- But nothing specific about S and T relative to each other.
- Statement 2: U is taller than Q but shorter than S, although Q is not the shortest.
- So, S > U > Q. Q is not the shortest, so there is someone else shorter than Q.
- Nothing about T here.
- Combining Both:
- Even when we combine: We know P > R > (Q/S/T/U in some order) and S > U > Q, but T’s height relative to S is not directly established in either. No way to compare S and T concretely.
- Option Explanation:
- Option 1: Not sufficient (lack of information about S & T relative to one another).
- Option 2: Not sufficient (doesn’t mention T).
- Option 3: Sufficient—Neither statement, together or alone, lets us compare S and T.
- Option 4: Not sufficient, as explained.
Correct Answer:
Option 3: Both 1 and 2 are not sufficient.
