Logical Reasoning Sufficiency

Q: Among five people (A, B, C, D, E) sitting in a row facing North, who sits exactly in the middle? I. A sits second to the left of B. II. C sits exactly between A and B.

Correct Answer: Option D (Statements I and II together are not sufficient.). Statements I and II together give the sequence A - C - B. However, we do not know where D and E are placed in the 5-seat row. The middle person cannot be uniquely determined. Not sufficient.

Q: Who sits at the extreme right end of a row of 5 people facing North? I. P sits at the extreme left end and Q is second to the right of P. II. S sits to the immediate left of T, w...

Correct Answer: Option B (Statement II alone is sufficient, but Statement I alone is not.). Statement I does not define the extreme right. Statement II explicitly states that T sits at the extreme right. Statement II alone is sufficient.

Q: How many people are sitting in the row facing North? I. X sits 5th from the left end and 7th from the right end. II. Y sits exactly in the middle of the row.

Correct Answer: Option A (Statement I alone is sufficient, but Statement II alone is not.). From Statement I, the total number of people is (5 + 7 - 1) = 11. Statement I alone is sufficient. Statement II provides no numerical data.

Q: Are X and Y sitting adjacent to each other in a straight row of 3 people? I. Z sits exactly between X and Y. II. X sits at the extreme left.

Correct Answer: Option A (Statement I alone is sufficient, but Statement II alone is not.). From Statement I, the arrangement is X-Z-Y or Y-Z-X. In either case, X and Y are separated by Z and are NOT adjacent. This provides a definitive 'No'. Statement I alone is sufficient.

Q: Among five friends (P, Q, R, S, T) sitting in a row facing South, who sits to the immediate right of Q? I. P sits at the exact center. II. Q sits at the extreme left end (from th...

Correct Answer: Option D (Statements I and II together are not sufficient.). Facing South reverses left/right. Extreme left for an observer means extreme right for the people in the row. However, we do not know who is sitting adjacent to Q. Not sufficient.
