Show answer & explanation
Correct answer: A
In a single-row seating arrangement, each person's position is an absolute count from one end of the row. Saying someone is 'Nth from an end' fixes their position directly; saying a person is 'X to the right of' another adds X to that person's position, and 'X to the left of' subtracts X. When a person sits at the extreme end of the row, their position number itself is the total number of people in the row.
Rita is 5th from the left end, so Rita's position = 5.
Sita is 11th to the right of Rita, so Sita's position = 5 + 11 = 16.
Tina is 4th to the left of Sita, so Tina's position = 16 − 4 = 12.
Madhuri is 8th to the right of Tina, so Madhuri's position = 12 + 8 = 20.
Since Madhuri is stated to be sitting at the extreme end of the row, her position number equals the total count of students — confirming there are 20 students in the row.
