Question: When I arrived at the theatre, Vinay was already there but Vijay was not there. Prabhat came after me and exactly one of the Prabhat and Prakash was there at the theatre when I arrived and exactly one person arrived between their arrivals. Who arrived last?

A: Prabhat
B: Prakash
C: Vinay
D: Vijay

Ans: D
Solution: The correct order of arrival is:
Vinay, Prakash, me, Prabhat, Vijay

When I reached there Vijay was not there but Vinay was. So Vinay came before me.
Prabhat came after me and exactly one of the Prabhat and Prakash was there at the theatre when I arrived. So the order of arrival of the three was: Prakash, me, Prabha.
And Vijay didn't come before me.
So the order is: Vinay, Prakash, me, Prabhat, Vijay
Vijay is the last person to arrive.
