Question 1

In a queue of 30 people, Arun is 10th from the front. What is his position from the back?

Accepted Answer

Position from back = Total people - Position from front + 1 = 30 - 10 + 1 = 21.

Question 2

In a row of 25 students, Raj is 8th 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: Position from right = Total students - Position from left + 1. Here: 25 - 8 + 1 = 18.

Question 3

In a class of 40 students arranged in a line, Priya is 15th from the left and Zara is 20th from the left. How many students are there between Priya and Zara?

Accepted Answer

Number of students between two people = Difference of their positions - 1. Here: |20 - 15| - 1 = 5 - 1 = 4 students.

Question 4

In a ranking of 50 athletes, Vikram is 12th from the top. If 5 athletes are disqualified from positions 1 to 10, what will be Vikram's new rank from the top?

Accepted Answer

Vikram is at position 12, which is beyond the disqualified range (1-10). His rank remains unchanged at 12th from the top.

Question 5

In a row of 35 students, Neha is 14th from the left and Meera is 14th from the right. How many students are between Neha and Meera?

Accepted Answer

Meera's position from left = 35 - 14 + 1 = 22. Students between them = |22 - 14| - 1 = 8 - 1 = 7.

Question 6

In a class of 45 students, Raj's rank from the top is 12th. What is Raj's rank from the bottom?

Accepted Answer

To find rank from bottom when rank from top is given: Rank from bottom = Total students - Rank from top + 1. Here: 45 - 12 + 1 = 34th from bottom.

Question 7

In a row of 25 students, Rajesh is 9th from the left end. Priya is 7 positions to the right of Rajesh. What is Priya's position from the right end?

Accepted Answer

This question tests the ability to determine absolute positions in a linear arrangement using relative positioning information.

Question 8

In a ranking of 50 employees by performance, Amit is ranked 15th from the top and Bhavna is ranked 20th from the bottom. How many employees are ranked between Amit and Bhavna (not including either of them)?

Accepted Answer

This question requires converting both top and bottom rankings to a common reference frame, then calculating the gap.

Question 9

In a queue of 60 people, Vikram is 25th from the front. If 8 people leave the queue from behind Vikram (not including Vikram), what is Vikram's new position from the front?

Accepted Answer

This tests understanding that removing people behind a person does not change their position from the front.

Question 10

In a line of 45 students, Neha is 16th from the left. Pooja is 12 positions to the right of Neha. What is Pooja's position from the right end?

Accepted Answer

This combines relative positioning with conversion between left and right rankings.

Question 11

In a row of 40 students, Rajesh is 12th from the left end. What is his position from the right end?

Accepted Answer

This is a basic number ranking problem requiring conversion between left and right positions in a linear arrangement.

Question 12

In a class of 35 students arranged in a row, Priya is 18th from the left. How many students are to the right of Priya?

Accepted Answer

This question tests understanding of the relationship between position and count of students on either side.

Question 13

In a row of 25 students, Priya is 9th from the left end. If Priya is shifted 4 positions to the right, what will be her position from the right end?

Accepted Answer

Step 1: Priya's initial position from left = 9th
Step 2: After shifting 4 positions to the right, Priya's new position from left = 9 + 4 = 13th
Step 3: Total students in the row = 25
Step 4: Position from right end = Total students - Position from left + 1
Step 5: Position from right end = 25 - 13 + 1 = 13th from the right
Alternatively: If she is 13th from left, then 25 - 13 = 12 students are to her right, making her 13th from the right end (counting herself).
Therefore, Priya's position from the right end = 13th

Question 14

In a class of 30 students, students are ranked by marks from highest to lowest. Priya is ranked 12th. If 8 students score more marks than Priya, and 15 students score less marks than Priya, how many students scored the same marks as Priya?

Accepted Answer

This question tests the ability to reconcile rank position with the actual distribution of scores, accounting for ties.

Question 15

In a competition, 20 participants are ranked 1 to 20 based on their scores. Participant A is ranked 8th. If the top 5 participants are given gold medals and the next 10 participants (ranks 6-15) are given silver medals, and Participant A's score is recalculated and increases by 15%, their new rank becomes 6th. How many participants had scores between Participant A's original score and their new score?

Accepted Answer

This question tests understanding of rank changes due to score modifications and the relationship between score intervals and participant counts.

Question 16

In a ranking of 12 students, Raj is 5 positions below Priya. If Priya is ranked 3rd from the top, what is Raj's rank from the bottom?

Accepted Answer

This question tests the ability to convert between top-to-bottom and bottom-to-top rankings while handling positional offsets.

Question 17

Seven people are standing in a row. When ranked by height from tallest to shortest, Arun is 4th. When ranked by age from oldest to youngest, Arun is 5th. If no two people share the same height or age, and Arun's position changes by exactly 1 when switching from height-ranking to age-ranking, how many people are taller than Arun but younger than him?

Accepted Answer

This question combines two independent ranking systems and requires logical deduction about the overlap between them.

Question 18

In a row of 40 students, Rajesh is 12th from the left end. Priya is 8 positions to the right of Rajesh. Vikram is 5 positions to the left of Priya. If 6 students leave the row from positions between Vikram and Priya (exclusive), what is Vikram's new position from the left end?

Accepted Answer

This is a hard number ranking question requiring students to: (1) establish initial positions, (2) account for removals in a specific range, (3) recalculate position after deletion. The trap involves miscounting the affected range or incorrectly applying the 'exclusive' constraint.

Question 19

In a ranking system, 25 people are ranked 1 to 25. Person X is ranked 10th. If we reverse the ranking (so rank 1 becomes rank 25, rank 2 becomes rank 24, etc.), and then we select the top 8 people from the reversed ranking, how many people are in both the original top 8 and the reversed top 8?

Accepted Answer

This question tests the ability to understand ranking reversal and find the intersection of two rank-based subsets.
