Question 1

In a queue of 30 people, Arun is 10th from the front. How many people are behind Arun?

Accepted Answer

If Arun is 10th from front, then 9 people are in front of him. People behind = Total - Position = 30 - 10 = 20.

Question 2

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: Position from right = Total students - Position from left + 1. Here: 25 - 8 + 1 = 18.

Question 3

In a class of 35 students arranged in a row, Arun is 12th from the left and Bhavna is 18th from the left. How many students are sitting between Arun and Bhavna?

Accepted Answer

Arun is at position 12 and Bhavna is at position 18. The number of students between them = 18 - 12 - 1 = 5 students.

Question 4

In a class of 40 students, Priya is 15th from the left and Anita is 12th from the right. How many students are between them?

Accepted Answer

Priya is 15th from left. Anita is 12th from right, so she is (40 - 12 + 1) = 29th from left. Students between them = 29 - 15 - 1 = 13.

Question 5

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

Accepted Answer

To find position from the right end when position from left end is known, use the formula: Position from right = Total number of students - Position from left + 1. Here: 25 - 8 + 1 = 18.

Question 6

In a line of 35 students, Neha is 12th from the left and Deepa is 18th from the left. How many students are between Neha and Deepa?

Accepted Answer

Neha is at position 12, Deepa is at position 18. Students between them = 18 - 12 - 1 = 5 (we subtract 1 to exclude both boundary persons).

Question 7

In a line of 60 people, Chirag is 25th from the left end and Deepak is 35th from the left end. How many people are standing between them?

Accepted Answer

Chirag is at position 25 and Deepak is at position 35. The number of people between them = 35 - 25 - 1 = 9 people.

Question 8

In a row of 25 students, Raj is 8th from the left end. What is Raj's position from the right end?

Accepted Answer

To find position from the right end, subtract the position from the left from the total number of students plus 1. Position from right = 25 - 8 + 1 = 18.

Question 9

In a ranking of 50 students, Divya is ranked 22nd from the top. What is her rank from the bottom?

Accepted Answer

Rank from bottom = Total students - Rank from top + 1 = 50 - 22 + 1 = 29th from the bottom.

Question 10

In a queue of 40 people, Priya is 15th from the front. How many people are standing behind Priya?

Accepted Answer

If Priya is 15th from the front, then 14 people are in front of her. The number of people behind her = Total - Position = 40 - 15 = 25 people.

Question 11

In a row of 20 students, Ramesh is 8th from the left end. What is his position from the right end?

Accepted Answer

Formula: Position from right = Total students – Position from left + 1. So, position from right = 20 – 8 + 1 = 13. Ramesh is 13th from the right end. Common mistake: forgetting to add 1, giving 12.

Question 12

In a line of 35 students, Vikram is 14th from the left and Sneha is 18th from the right. What is the position of Sneha from the left?

Accepted Answer

Sneha is 18th from the right. Using the conversion formula: Position from left = Total - Position from right + 1 = 35 - 18 + 1 = 18th from left.

Question 13

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, use the formula: Position from right = Total number - Position from left + 1. Here: 25 - 8 + 1 = 18.

Question 14

In a queue of 50 people, Amit is 20th from the front. Bhavna is 15th from the back. How many people are between Amit and Bhavna?

Accepted Answer

Amit is 20th from front. Bhavna is 15th from back, so she is (50 - 15 + 1) = 36th from front. People between them = 36 - 20 - 1 = 15.

Question 15

In a class of 40 students, Priya ranks 12th from the top. How many students rank below her?

Accepted Answer

If Priya is 12th from the top, then 11 students are above her. Students below her = Total - Position from top = 40 - 12 = 28.

Question 16

In a row of 25 students, Raj is 9th from the left end. What is Raj's position from the right end?

Accepted Answer

This is a fundamental number ranking problem testing the ability to convert position from one end to the opposite end using the formula: Position from right = Total count - Position from left + 1.

Question 17

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 ranking problem requiring conversion between left and right positions. The formula is: Position from right = Total - Position from left + 1. Here: 40 - 12 + 1 = 29.

Question 18

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

Accepted Answer

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

Question 19

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 ranking problem requiring conversion between left and right positions in a linear arrangement.

Question 20

In a queue of 45 people, Vikram is 16th from the front. If 3 people leave from the front of the queue (before Vikram) and 2 people join at the back, what is Vikram's new position from the front?

Accepted Answer

This tests number ranking with multiple dynamic changes—removals from one end and additions at another end—requiring careful constraint tracking.
