Ordering and Ranking

Q: What is the total number of children in the row? I. P is 15th from the left and Q is 20th from the right. II. After they interchange their positions, P becomes 25th from the left...

Correct Answer: Option C (Both statements together are sufficient, but neither statement alone is sufficient.). From I and II, initially P is 15th from left. After interchanging with Q, P becomes 25th from left. P's new position (25th from left) is Q's old position. From I, Q is 20th from right. Total = (25 + 20) - 1 = 44. Both statements are required.

Q: What is A's new position from the right end after interchanging places with B? I. A is 10th from the left and B is 15th from the right. II. After interchanging, B becomes 20...

Correct Answer: Option C (Both statements together are sufficient, but neither statement alone is sufficient.). From I, A is 10th from left, B is 15th from right. After interchange, B becomes 20th from right. B's new position is A's old position. So A's old position is 20th from right and 10th from left. Total = 20 + 10 - 1 = 29. A's new position is B's old position, which is 15th from right. Both are required.

Q: How many people are sitting between X and Y? I. X is 12th from the left end and Y is 18th from the right end. II. After interchanging their positions, X becomes 20th from the lef...

Correct Answer: Option C (Both statements together are sufficient, but neither statement alone is sufficient.). From I, initially X is 12th from left. From II, after interchange, X becomes 20th from left. The number of people strictly between them is (New position - Old position) - 1 = (20 - 12) - 1 = 7. Both are required.

Q: What is the position of Y from the right end after the interchange? I. X is 8th from the left. After interchanging with Y, X becomes 15th from the left. II. There are exactly 6 p...

Correct Answer: Option D (Statements I and II together are not sufficient.). From I, X is 8th from left. After interchange, X is 15th from left. This gives total distance, but we don't know Y's initial position from the right. Statement II says there are 6 people between them, which aligns with (15-8-1=6), but still gives no anchor to the right end. Not sufficient.

Q: Who is sitting immediately to the right of P after the interchange? I. P is 5th from left and Q is 10th from right. After interchange, P is 12th from left. II. R is 11th from the...

Correct Answer: Option D (Statements I and II together are not sufficient.). The statements only provide numerical ranks and distances. Without specific arrangements or names of adjacent individuals, it's impossible to identify exactly 'who' is sitting next to P. Not sufficient.
