Question

In a queue, Shikhar is 9th from the back. Arun’s place is 8th​ from the front. Nikhil is standing between the two. What could be the minimum number of boys standing in the queue?


  1. 9

  2. 8

  3. 10

  4. 12


Solution

The correct option is C

10


The maximum given rank for a boy from one side of the queue is 9. So, we first consider a queue of 9 boys.

1 2 3 4 5 6 7 8 9

S                  A

But in this queue, there are even number of boys between Shikhar and Arun and as such, the middle position of Nikhil cannot be ascertained.

Now, consider an arrangement of 10 boys in a queue.

1 2 3 4 5 6 7 8 9 10

 S        N       A

Hence, the required number of students = 10
