- In a row of 36 people, A is 18th from right and B is 10th from the left. Then find How many people are in between A and B?
- 5 People
- 8 People
- 10 People
- 12 People

Answer: (b) 8 People

Solution: Number of people between A and B = [Total number of persons - (Position of A from right + Position of B from left)]

= 36 - (18 + 10)

= 8 People

Solution: Number of people between A and B = [Total number of persons - (Position of A from right + Position of B from left)]

= 36 - (18 + 10)

= 8 People

- Rita is 8th from the left and Ritika is 12th from the right. When they interchange their position respectively, then Rita becomes 14th from the left. Then what will be the position of Ritika from right after interchange?
- 10th
- 12th
- 18th
- 20th

Answer: (c) 18th

Solution: Total number of persons = [(Position of Rita from right end after interchange + Position of Rita from left end after interchange) - 1]

= [(12 + 14) - 1] = 25

Rank of Ritika from right end after interchange = [(Total number of persons - Rank of Ritika from left end after interchange) + 1]

= [(25 - 8) + 1] = 18th

Solution: Total number of persons = [(Position of Rita from right end after interchange + Position of Rita from left end after interchange) - 1]

= [(12 + 14) - 1] = 25

Rank of Ritika from right end after interchange = [(Total number of persons - Rank of Ritika from left end after interchange) + 1]

= [(25 - 8) + 1] = 18th

- In a row of 25 persons, P is 16th from right and Q is 4th from the left. Then find How many people are in between P and Q?
- 5 Persons
- 6 Persons
- 7 Persons
- 8 Persons

Answer: (a) 5 Persons

Solution: Number of persons between P and Q = [Total number of persons - (Position of P from right + Position of Q from left)]

= 25 - (16 + 4)

= 5 Persons

Solution: Number of persons between P and Q = [Total number of persons - (Position of P from right + Position of Q from left)]

= 25 - (16 + 4)

= 5 Persons

- In a row of 43 persons, P is 15th from the right end and Q is 17th from the left end. R is sitting exactly between P and Q. Then, what is the position of R from the left end?
- 20th
- 22nd
- 23rd
- 25th

Answer: (c) 23rd

Solution: Number of persons between P and Q = [Total number of persons - (Position of P from right + Position of Q from left)]

= 43 - (15 + 17) = 11

exact middle position = [(Number of persons between P and Q + 1)/2]

= [(11 + 1)/2] = 6

Position of R from left end = [position of Q from left end + Number of persons between P and Q]

= 17 + 6 = 23rd

Solution: Number of persons between P and Q = [Total number of persons - (Position of P from right + Position of Q from left)]

= 43 - (15 + 17) = 11

exact middle position = [(Number of persons between P and Q + 1)/2]

= [(11 + 1)/2] = 6

Position of R from left end = [position of Q from left end + Number of persons between P and Q]

= 17 + 6 = 23rd

- In a row Ram is 15th from the left and 11th from the right. Then find the total number of persons in the row?
- 20
- 25
- 30
- 35

Answer: (b) 25

Solution: Total number of persons = [(Position of Ram from left + Position of Ram from right) - 1]

= [(15 + 11) - 1] = 25

Solution: Total number of persons = [(Position of Ram from left + Position of Ram from right) - 1]

= [(15 + 11) - 1] = 25

- In a row of 23 persons, Vikash is 10th from the right. Then find the position of Vikash from left end?
- 10
- 12
- 14
- 16

Answer: (c) 14

Solution: Position of Vikash from left = [(Total number of persons - Position of vikash from right) + 1]

= [(23 - 10) + 1] = 14

Solution: Position of Vikash from left = [(Total number of persons - Position of vikash from right) + 1]

= [(23 - 10) + 1] = 14

- In a row of 49 women, P is 18th from the right end and Q is 14th from the left end. Then find how many women are in between P and Q?
- 15
- 17
- 19
- 21

Answer: (b) 17

Solution: Number of women between P and Q = [Total number of women - (Position of P from right + Position of Q from left)]

= 49 - (18 + 14) = 17

Solution: Number of women between P and Q = [Total number of women - (Position of P from right + Position of Q from left)]

= 49 - (18 + 14) = 17

- In a row of 32 students, A is 13th from the left. Then find the position of A from right end?
- 12th
- 15th
- 20th
- 25th

Answer: (c) 20th

Solution: Position of A from right = [(Total number of students - Position of A from left) + 1]

= [(32 - 13) + 1] = 20

Solution: Position of A from right = [(Total number of students - Position of A from left) + 1]

= [(32 - 13) + 1] = 20

- In a row, P is 16th from the left and 17th from the right. Then find the total number of persons in the row?
- 25
- 28
- 32
- 35

Answer: (c) 32

Solution: Total number of persons = [(Position of P from left + Position of P from right) - 1]

= [(16 + 17) - 1] = 32

Solution: Total number of persons = [(Position of P from left + Position of P from right) - 1]

= [(16 + 17) - 1] = 32

- In a row of 39 boys, A is 13th from left and B is 15th from the right. Then find How many people are in between A and B?
- 10
- 11
- 12
- 13

Answer: (b) 11

Solution: Number of boys between A and B = [Total number of boys - (Position of A from left + Position of B from right)]

= 39 - (13 + 15) = 11

Solution: Number of boys between A and B = [Total number of boys - (Position of A from left + Position of B from right)]

= 39 - (13 + 15) = 11
