Question 1
In a row of 40 students, Karan's rank from the right end is 25. What is Karan's rank from the left end?
The total number of people T = 40. Rank from left L = T - R + 1 = 40 - 25 + 1 = 16. So, Karan's rank from the left is 16.

Question 2
19 people are sitting around a circular table. Person A is at position 16 and Person B is at position 12 (when numbered clockwise from 1 to 19). What is the minimum number of people between A and B?
Clockwise distance: 15 steps, Anti-clockwise: 4 steps. Minimum people between = min(15, 4) - 1 = 3.
Question 3
In a queue, Lata is 16th from the front and Nisha is 21th from the back. If there are 9 people standing between them, what is the total number of people in the queue?
Overlapping case: Total T = (r1 + r2) - B - 2 = 37 - 9 - 2 = 26.
Question 4
In a row of 50 students, B is 23th from the left and D is 29th from the left. How many students are between them?
Between = |29 - 23| - 1 = 6 - 1 = 5.
Question 5
In a row, Pooja is 16th from the left and Rohit is 17th from the right. If Rohit is 22th from the left, how many people are there in the row?
Using T = L + R - 1 with Rohit's left rank 22 and right rank 17: T = 22 + 17 - 1 = 38.
Question 6
In a row, A and B interchange positions. After interchange, A is 11th from left and B is 17th from left. If originally A was 4th from left, how many people are in the row?
Distance A moved = 7 positions. B moved same distance, so B's original position = 10. Total = B's original left position + (new_left_A - 1) = 24
Question 7
In a row of 41 people, Tanvi is 16th from the front and Yash is 34th from the front. How many people are between them?
Between B = (rank of second - rank of first - 1) = 34 - 16 - 1 = 17.
Question 8
In a class, Ishita has 21 students ahead of him and 11 students behind him. What is the total number of students in the class?
Total = ahead + behind + 1 = 21 + 11 + 1 = 33.
Question 9
In a row, A and B interchange positions. After interchange, A is 9th from left and B is 16th from left. If originally A was 5th from left, how many people are in the row?
Distance A moved = 4 positions. B moved same distance, so B's original position = 12. Total = B's original left position + (new_left_A - 1) = 20
Question 10
In an exam, 98 students appeared. Rahul secured 35th rank. What is Rahul's approximate percentile?
Percentile = (Number of students below / Total) × 100 = (63/98) × 100 = 64.3%
Question 11
In a row, A and B interchange positions. After interchange, A is 10th from left and B is 17th from left. If originally A was 5th from left, how many people are in the row?
Distance A moved = 5 positions. B moved same distance, so B's original position = 12. Total = B's original left position + (new_left_A - 1) = 22
Question 12
In an exam, 56 students appeared. 2 students scored the same marks and secured the 42th rank. How many students scored more than them?
Even though 2 students share the rank, the number of students who scored more is still rank - 1 = 42 - 1 = 41.
Question 13
In a class of 26 students, Kunal ranks 5th from the top. How many students are behind Kunal?
Students behind = total - rank = 26 - 5 = 21.
Question 14
In a row of 48 people, Arun is 11th from the left. If Bhavya is 34th from the right, what is Bhavya's rank from the left?
Rank from left L = T - R + 1 = 48 - 34 + 1 = 15.
Question 15
In an exam, 109 students appeared. Priya secured 9th rank. What percentage of students are behind Priya?
Students behind = 100. Percentage = (100/109) × 100 = 91.7%
Question 16
In a row of 47 people, A is 13th from the left. After interchanging positions with B, A becomes 21th from the left. B originally was 14th from the right. What is A's new rank from the right?
After interchange, A's new left rank is 21. So A's new right rank = total - new_left + 1 = 47 - 21 + 1 = 27.
Question 17
In a class of 60 students, there are 34 boys and 26 girls. Meera ranks 25th from the top. There are 8 boys before her in the rank list. How many girls are after her rank (towards the bottom)?
Students before her: 24. Of these, boys before = 8, so girls before = 24 - 8 = 16. Girls after = total girls - girls before - herself = 26 - 16 - 1 = 9.
Question 18
In a row of 43 people, Isha is 7th from the left. If Vikram is 35th from the right, what is Vikram's rank from the left?
Rank from left L = T - R + 1 = 43 - 35 + 1 = 9.
Question 19
In a row of 28 students, Simran's rank from the right end is 8. What is Simran's rank from the left end?
The total number of people T = 28. Rank from left L = T - R + 1 = 28 - 8 + 1 = 21. So, Simran's rank from the left is 21.
Question 20
In a class, Ved has 10 students ahead of him and 20 students behind him. What is the total number of students in the class?
Total = ahead + behind + 1 = 10 + 20 + 1 = 31.
