Logical Reasoning Sufficiency

Q: In a 5-person race, what was A's final position? I. B finished second. II. C finished immediately behind A and immediately ahead of D.

Correct Answer: Option C (Both statements together are sufficient, but neither statement alone is sufficient.). From II, we have a 3-person block: A - C - D. From I, B is 2nd. The block A-C-D cannot start at 1st or 2nd. It must occupy 3rd, 4th, and 5th. Thus, A finished 3rd. Both are required.

Q: Are the two straight lines parallel? I. They do not intersect at any point. II. They are coplanar (in the same plane).

Correct Answer: Option C (Both statements together are sufficient, but neither statement alone is sufficient.). By geometric logic, lines that do not intersect could be skew lines in 3D space. Statement II restricts them to the same plane. Coplanar lines that do not intersect are parallel. Both are required.

Q: Who is sitting opposite to P at a square table (4 people sitting at corners)? I. Q sits to the immediate right of P. II. R sits to the immediate left of P.

Correct Answer: Option D (Statements I and II together are not sufficient.). From I and II, P has Q on the right and R on the left. The person opposite P is the 4th person, but neither statement provides the name/identity of this 4th person. Not sufficient.

Q: Is today Sunday? I. Tomorrow is Monday. II. Yesterday was Saturday.

Correct Answer: Option D (Each statement alone is sufficient.). Statement I implies today is Sunday. Statement II implies today is Sunday. Both individually answer the question definitively with a 'Yes'. Each statement alone is sufficient.

Q: Which of the three boxes (Red, Blue, Green) contains the gold coin? I. The coin is not in the Red box. II. The Blue box is completely empty.

Correct Answer: Option C (Both statements together are sufficient, but neither statement alone is sufficient.). From I, the coin is in Blue or Green. From II, Blue is empty. Combining them leaves Green as the only possible location for the coin. Both are required.
