1. 12 People
2. 10 People
3. 8 People
4. 7 People

Answer: (c) 8 People

1. In a row, Kiran is 25th from the left and 17th from the right. Find the total number of people in the row?

1. 41
2. 42
3. 45
4. 47

Solution: Total number of people in the row = [(Position of Kiran from left + Position of Kiran from right) - 1]

= [(25 + 17) - 1] = 41

1. In a row of 30 people, Raj is 12th from the right. Find the position of Raj from the left end?

1. 12th
2. 15th
3. 18th
4. 19th

Solution: Position of Raj from left end = [(Total number of people - Position of Raj from right) + 1]

= [(30 - 12) + 1] = 19

Hence, Raj is 19th from the left end.

1. In a class of 55 students, Priya is ranked 25th from the top. When 5 new students joined the class, her rank dropped by two. What is her new rank from the bottom?

1. 30th
2. 32nd
3. 34th
4. 39th

Solution: Total number of students after five new students joined the class = 60

Since, the rank of Priya dropped by two, so the new rank is 27th from top.

Hence, the new rank of priya from the end = 60 - 27 + 1 = 34th.

Solution: Total number of students = 22

Rank of Hina from the top = 13th

Rank of Hina from the bottom = 22 - 13 + 1 = 10th.

1. In a row of people, Rakesh is 18th from the start and 20th from the end. In another row of people, Shikha is 15th from the start and 17th from the end. How many people are there in both the rows together?

1. 58
2. 62
3. 68
4. 72

Solution: In first row, total number of people = 18 + 20 - 1 = 37

In second row, total number of people = 15 + 17 - 1 = 31

Hence, total number of people in both the rows together = 37 + 31 = 68
