Question 1

In a row of 15 students, Priya's rank from the left is 7th. What is her rank from the right?

Accepted Answer

To find rank from the right when rank from left is given:
Rank from right = Total number of students - Rank from left + 1

Given:
- Total students = 15
- Rank from left = 7th

Rank from right = 15 - 7 + 1 = 9th

Verification: If Priya is 7th from left, there are 6 students to her left and 8 students to her right. So she is 9th from the right (8 + 1 = 9). ✓

Common mistakes students make:
- Option A (8th): Forgetting to add 1 in the formula
- Option C (6th): Subtracting from left rank from total
- Option D (15th): Confusing with total number of students

Question 2

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

Accepted Answer

This tests the fundamental number ranking concept of converting position from one end to the opposite end using the formula: Position from right = Total number - Position from left + 1. Here: 8 - 3 + 1 = 6.

Question 3

In a class of 25 students, Priya is 8th from the left. How many students are to the right of Priya?

Accepted Answer

This tests understanding that the number of students to the right = Total students - Position from left. Here: 25 - 8 = 17 students are to the right of Priya.

Question 4

In a queue of 12 people, Amit is 5th from the left and Bhavna is 5th from the right. How many people are between Amit and Bhavna?

Accepted Answer

This tests ranking with two positions. Bhavna's position from left = 12 - 5 + 1 = 8. People between them = 8 - 5 - 1 = 2 (excluding both Amit and Bhavna).

Question 5

In a ranking of 20 students, Vikram is 12th from the top. What is his rank from the bottom?

Accepted Answer

This tests rank conversion from top to bottom. Rank from bottom = Total students - Rank from top + 1 = 20 - 12 + 1 = 9.

Question 6

In a line of 15 children, Neha is 7th from the left and Isha is 7th from the right. Are they at the same position or different positions?

Accepted Answer

This tests understanding of symmetry in ranking. Neha is 7th from left. Isha is 7th from right, which means she is at position (15 - 7 + 1) = 9 from the left. Since 7 ≠ 9, they are at different positions.

Question 7

In a row of 25 students, Rajesh is 8th from the left. What is his 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: 25 - 8 + 1 = 18.

Question 8

In a queue of 40 people, Priya is 12th from the front. How many people are standing behind her?

Accepted Answer

If Priya is 12th from the front, there are 11 people in front of her. Total people behind her = 40 - 12 = 28.

Question 9

In a class of 35 students arranged in a row, Arjun is 15th from the left and Neha is 20th from the left. How many students are sitting between them?

Accepted Answer

Arjun is at position 15, Neha is at position 20. The number of students between them = 20 - 15 - 1 = 4 students.

Question 10

In a ranking of 50 students, Vikram is ranked 18th from the top. What is his rank from the bottom?

Accepted Answer

Using the formula: Rank from bottom = Total students - Rank from top + 1. Here: 50 - 18 + 1 = 33.

Question 11

In a line of 60 people, Deepak is 25th from the left. Kavya is 30th from the right. How many people are between Deepak and Kavya?

Accepted Answer

Deepak is 25th from left. Kavya is 30th from right, which means she is (60 - 30 + 1) = 31st from left. People between them = 31 - 25 - 1 = 5.

Question 12

In a merit list of 60 students, Neha's rank is 25th from the top. If 8 students below her in the list leave the institution, what will be her new rank from the bottom?

Accepted Answer

This combines two concepts: tracking rank changes when students leave, and converting between top and bottom rankings in a reduced list.

Question 13

In a tournament, 7 players are ranked. Vikram is ranked 4th. If the rankings are reversed (1st becomes last, 2nd becomes second-last, etc.), what will be Vikram's new rank?

Accepted Answer

This tests understanding of rank reversal—a conceptual shift where the ranking order is completely inverted.

Question 14

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 15

In a merit list of 45 students, Shreya's rank from the top is 12th and Pooja's rank from the bottom is 8th. How many students rank between Shreya and Pooja (not including them)?

Accepted Answer

This tests the ability to work with mixed rankings (top and bottom) and calculate the gap between two positions.

Question 16

In a class ranking, Priya is 8th from the top and 15th from the bottom. How many students are in the class?

Accepted Answer

This question tests the ability to use positional information from both ends to determine total count in a ranking.

Question 17

In a queue of 60 people, Vikram is 18th from the front. Exactly 5 people stand between Vikram and Deepak. If Deepak is behind Vikram, what is Deepak's position from the front?

Accepted Answer

This question tests the ability to calculate position when the number of people between two individuals is given, with directional constraint.

Question 18

In a queue of 50 people, Amit is 18th from the front. If 5 people leave from the front of the queue before Amit, what will be Amit's new position from the front?

Accepted Answer

This tests dynamic ranking—understanding how a person's position changes when others are removed from the queue.

Question 19

In a class of 35 students arranged in a line, Divya is 14th from the left. If 5 students are removed from positions 1 to 13 (from the left), what will be Divya's new position from the left?

Accepted Answer

Divya is initially 14th from the left. When 5 students from positions 1-13 are removed, all students from position 14 onwards shift left by 5 positions. Divya's new position: 14 - 5 = 9.

Question 20

In a queue of 48 people, Neha is 19th from the front. Rohan is 22nd from the back. If Neha and Rohan swap positions, how many people will be between them in their new arrangement?

Accepted Answer

Neha is 19th from front. Rohan is 22nd from back = 48 - 22 + 1 = 27th from front. After swap: Neha is at 27, Rohan is at 19. People between = 27 - 19 - 1 = 7.
