Question 1

In a row of 12 chairs, the red chair is 5th from the left. The blue chair is 4th from the right. How many chairs are between the red and blue chairs?

Accepted Answer

Red chair: 5th from left. Blue chair: 4th from right = 12 - 4 + 1 = 9th from left. Chairs between = |9 - 5| - 1 = 4 - 1 = 3 chairs.

Question 2

In a queue of 15 people, Arun is 7th from the front. How many people are standing behind Arun?

Accepted Answer

If Arun is 7th from the front in a queue of 15, then the number of people behind him = Total - Position from front = 15 - 7 = 8.

Question 3

In a class ranking, Priya is ranked 12th from the top and 19th from the bottom. How many students are in the class?

Accepted Answer

When a person is ranked from both ends, total = rank from top + rank from bottom - 1. Here: 12 + 19 - 1 = 30.

Question 4

In a line of 20 students, Neha is 8th from the left and Zara is 12th from the left. How many students are standing between Neha and Zara?

Accepted Answer

Number of students between two people = Difference of their positions - 1. Here: |12 - 8| - 1 = 4 - 1 = 3 students.

Question 5

In a row of 8 students, Raj is 3rd from the left. What is Raj's position from the right?

Accepted Answer

To find position from the right when position from left is known, use the formula: Position from right = Total number - Position from left + 1. Here: 8 - 3 + 1 = 6.

Question 6

In a ranking of 25 athletes, Vikram is ranked 10th from the top. If 3 athletes are disqualified from the top, what will be Vikram's new rank from the top?

Accepted Answer

If athletes ranked above Vikram are removed, his rank improves (decreases). Since 3 athletes from the top are disqualified, Vikram's new rank = 10 - 3 = 7th from the top.

Question 7

In a ranking list of 50 students, Vikram's rank is 18th from the top. If 3 students are added to the top of the ranking (above all current students), what will be Vikram's new rank from the top?

Accepted Answer

This tests understanding of how inserting new elements at a specific position affects the ranking of existing elements.

Question 8

In a row of 25 students, Rajesh is 8th from the left end. What is his position from the right end?

Accepted Answer

This is a basic ranking problem requiring conversion from one end to the opposite end using the formula: Position from right = Total - Position from left + 1

Question 9

In a class ranking, Priya is 12th from the top and 19th from the bottom. How many students are in the class?

Accepted Answer

This question tests the ability to find total count when positions from both ends are given using: Total = Position from top + Position from bottom - 1

Question 10

In a queue of 40 people, Arun is 15th from the front. If 5 people leave from the front of the queue before Arun, what will be Arun's new position from the front?

Accepted Answer

This tests dynamic ranking—understanding how position changes when elements before a person are removed from the sequence.

Question 11

In a row of students, Meera is 7th from the left and Neha is 9th from the right. If there are 20 students in total and both are in the same row, how many students are between them?

Accepted Answer

This tests the ability to find the number of elements between two ranked positions when both positions are given from opposite ends.

Question 12

In a row of 40 students, Rajesh is 12th from the left end. Priya is 8 positions to the right of Rajesh. What is Priya's position from the right end?

Accepted Answer

Priya is at position 20 from the left (12 + 8). In a row of 40, position from right = 40 - 20 + 1 = 21.

Question 13

Seven boxes are arranged in a line. Box P is 3rd from the left. Box Q is 2 positions to the right of Box P. Box R is exactly in the middle. How many boxes are between Box Q and Box R?

Accepted Answer

P is 3rd from left. Q is 2 positions right of P = 5th position. Middle of 7 boxes is 4th position (R). Between Q (5th) and R (4th) = 0 boxes (they are adjacent).

Question 14

In a ranking of 50 students by marks, Arun is 18th from the top. If 5 students are removed from the ranking (none of whom are Arun), how many students will be ranked below Arun in the new ranking?

Accepted Answer

Originally, 50 - 18 = 32 students are below Arun. After removing 5 students (not Arun), total becomes 45. Arun remains 18th from top, so 45 - 18 = 27 students are below him.

Question 15

In a class of 60 students, when ranked by height from tallest to shortest, Vikram is 25th. When the same students are ranked by weight from heaviest to lightest, Vikram is 20th. If we create a combined ranking where students are ordered by the sum of their height rank and weight rank (lower sum = better rank), what is Vikram's maximum possible rank in the combined ranking?

Accepted Answer

Vikram's height rank = 25, weight rank = 20. Sum = 45. In best case, no other student has a sum ≤ 44. Maximum rank = 1 (if he's the only one with sum 45 or if all others have higher sums). But realistically, his rank is determined by how many have sum < 45. Minimum possible rank = 1 (best case), maximum = 45 (worst case if all others have sum ≤ 44).

Question 16

In a tournament with 8 teams, Team A finished 3rd. In a separate tournament with 12 teams, Team B finished 5th. If we rank these teams together (treating the tournaments as equivalent), what is the minimum number of teams that must rank below both Team A and Team B?

Accepted Answer

Team A is 3rd out of 8 (5 teams below A). Team B is 5th out of 12 (7 teams below B). Minimum teams below both = teams that are below both A and B. In best case, all 5 teams below A are also among the 7 teams below B. Minimum below both = max(5, 7) - overlap. Minimum = 7 - 5 = 2 (when all 5 below A are within the 7 below B).

Question 17

In a line of 35 people, Neha is 14th from the left. Mohan is 11th from the right. Between Neha and Mohan, there are exactly 6 people. What is the distance (in positions) between Neha and Mohan?

Accepted Answer

Neha is 14th from left. Mohan is 11th from right = 35 - 11 + 1 = 25th from left. If there are exactly 6 people between them, positions are 14 and 25. Distance = 25 - 14 - 1 = 10 (but this counts people between). Distance in positions = 25 - 14 = 11.
