In a queue, Shekhar is ninth from the rear end. Arun's place is eighth from the front. Nikhil is standing between the two. What could be the minimum numbers of boys standing in the queue?

• there are two ways
  first way: 1 2 3 4 5 6 7 8(ARUN) 9(Nikhil) 10(SHEKHAR) 11 12 13 14 15 16 17 18
  Here, Arun is 8th from front, Shekhar is 9th from rear end and Nikhil is between them
  
  So no. of boys standing in the queue = 18
  
  Second way (MINIMUM)
  
  1 2 3 4 5 6(Shekhar) 7(Nikhil) 8(Arun) 9 10 11 12 13 14
  Here, Arun is 8th from front, Shekhar is 9th from rear end and Nikhil is between them
  So minimum no. of boys standing in the queue = 14

• maximium rank given for a boy is 9 so first take 9 numbers initialy
  
  1 2 3 4 5 6 7 8 9
  s A
  
  in this there are add numbers between shikar and arun and as such the middle position of nikhil cannot be ascertained.
  now consider an arrangement of 10 numbers
  
  1 2 3 4 5 6 7 8 9 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, required number of students = 10.

  from the front = 8
  
  9th from rear end = వెనుక భాగంలో నుండి 9 వ =======> i.e., from the back count is started = 9
  
  in middle Nikil is standing......
  
  Hence total 8+1+9

• 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19...
  (shekhar) (nikhil) Arun (nikhil) (shekhar)
  
  since Arun's position is fixed at 8 A/Q.
  
  Now, Shekhar and Nikhil should be either at 6 and 7 or at 9 and 10 respectively for nikhil to be positioned in the middle.
  
  Since it has been asked for minimum number of boys, so Nikhil's place should be before Arun to minimize the total number.
  Now for Shekhar to be on the nineth position from the rear end and also for Nikhil to be in the middle, the total number of boys should be 14 and Shekhar's should be placed at 6th position from the beginning.
  
  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19...
  shekhar nikhil Arun
  
  Therefore, the required answer is 14.

• i think min no of student should be 9
  
  starting from front Arun's place is 8th so
  1 2 3 4 5 6 7 8(Arun)
  and sekhar is 9th from the rear so
  (shekhar)9 8 7 6 5 4 3 2 1
  now from left to right and right to left
  (sekhar)1 2 3 4 5 6 7 8(arun)9
  sekhar may be first position from starting

• Shekhar is 9th from rear end
  Arun is 8th from front end
  Nikhil is between them
  
  So, Person before shekhar would be 8 and adding shekhar it would be total 9
  
  on the other side from front end including arun total person standing are 8
  
  and nikhil is between them which is count as 1 in queue
  
  So, 9+8+1=18
  
  Ans =18 minimum number of boys should be there.

• Since they mentioned it as queue take the general example of queue in stack.
  There are 9 places from rear and from front arun is at 8th position. But taking 8 we wont get Nikhil in middle.
  So the answer is 8+1=9

• In The question MINIMUM number of boys is asked
  so, now consider
  
  (1,2,3,4,5,6(ARUN),7(NIKHIL),8(SHEKHAR),9, 10, 11 ,12, 13, 14)
  now, Shekhar is in 9th place from rear, arun is in 8th place from front and nikhil is placed between them. All conditions are satisfied.
  so, MINIMUM NO OF BOYS ARE 14
