Worksheet 10 of 10 (100% complete)

Question 1

In a row, Amit is 11th from the left and Tarun is 21th from the right. They interchange their positions. Now, Amit becomes 16th from the left. What is the total number of people in the row?
When positions are interchanged, using one person's rank from the left and the other's rank from the right at the interchanged positions: T = L + R - 1 = 16 + 21 - 1 = 36.

Question 2

In a row, Chetan is 15th from the left and Tarun is 18th from the right. They interchange their positions. Now, Chetan becomes 19th from the left. What is the total number of people in the row?
When positions are interchanged, using one person's rank from the left and the other's rank from the right at the interchanged positions: T = L + R - 1 = 19 + 18 - 1 = 36.

Question 3

In a row, Divya is 14th from the left and Tarun is 22th from the right. They interchange their positions. Now, Divya becomes 21th from the left. What is the total number of people in the row?
When positions are interchanged, using one person's rank from the left and the other's rank from the right at the interchanged positions: T = L + R - 1 = 21 + 22 - 1 = 42.

Question 4

In a row, Bina is 14th from the left and Usha is 21th from the right. They interchange their positions. Now, Bina becomes 21th from the left. What is Usha's new rank from the right?
First find total: T = 21 + 21 - 1 = 41. After interchange, Usha takes Bina's old position from left (14). So Usha's rank from right = T - 14 + 1 = 41 - 14 + 1 = 28.

Question 5

In a row, Divya is 14th from the left and Usha is 21th from the right. They interchange their positions. Now, Divya becomes 21th from the left. What is Usha's new rank from the right?
First find total: T = 21 + 21 - 1 = 41. After interchange, Usha takes Divya's old position from left (14). So Usha's rank from right = T - 14 + 1 = 41 - 14 + 1 = 28.

Question 6

In a row, Divya is 13th from the left and Ramesh is 25th from the right. They interchange their positions. Now, Divya becomes 20th from the left. What is Ramesh's new rank from the right?
First find total: T = 20 + 25 - 1 = 44. After interchange, Ramesh takes Divya's old position from left (13). So Ramesh's rank from right = T - 13 + 1 = 44 - 13 + 1 = 32.

Question 7

In a row, Divya is 10th from the left and Tarun is 24th from the right. They interchange their positions. Now, Divya becomes 14th from the left. What is the total number of people in the row?
When positions are interchanged, using one person's rank from the left and the other's rank from the right at the interchanged positions: T = L + R - 1 = 14 + 24 - 1 = 37.

Question 8

In a row, Amit is 10th from the left and Sneha is 18th from the right. They interchange their positions. Now, Amit becomes 15th from the left. What is the total number of people in the row?
When positions are interchanged, using one person's rank from the left and the other's rank from the right at the interchanged positions: T = L + R - 1 = 15 + 18 - 1 = 32.

Question 9

In a row, Amit is 12th from the left and Usha is 18th from the right. They interchange their positions. Now, Amit becomes 18th from the left. What is Usha's new rank from the right?
First find total: T = 18 + 18 - 1 = 35. After interchange, Usha takes Amit's old position from left (12). So Usha's rank from right = T - 12 + 1 = 35 - 12 + 1 = 24.

Question 10

In a row, Chetan is 12th from the left and Usha is 21th from the right. They interchange their positions. Now, Chetan becomes 18th from the left. What is the total number of people in the row?
When positions are interchanged, using one person's rank from the left and the other's rank from the right at the interchanged positions: T = L + R - 1 = 18 + 21 - 1 = 38.

Question 11

In a row, Bina is 13th from the left and Ramesh is 24th from the right. They interchange their positions. Now, Bina becomes 18th from the left. What is Ramesh's new rank from the right?
First find total: T = 18 + 24 - 1 = 41. After interchange, Ramesh takes Bina's old position from left (13). So Ramesh's rank from right = T - 13 + 1 = 41 - 13 + 1 = 29.

Question 12

In a row, Divya is 15th from the left and Usha is 18th from the right. They interchange their positions. Now, Divya becomes 21th from the left. What is the total number of people in the row?
