Question 1
In a queue of 42 people, Ram is 12th from the left and Sita is 11th from the right. There is an odd number of people between them. Gita stands exactly in the middle of Ram and Sita. What is Gita's rank from the right?
Rank(Sita,L) = 42 - 11 + 1 = 32. Between = 32 - 12 - 1 = 19 (odd). Gita is central, so Rank(Gita,L) = 12 + (19//2) + 1 = 22. Rank(Gita,R) = 42 - 22 + 1 = 21.
