(a) 3
(b)5
(c )1
(d)4
(e)cannot be determined

Answers: 

1) GIVEN :

  • B/D - D/B (one person between B and D , here we do not know exact position of B and D ) 
  • C faces B 
  • A is to the right of C 
  • G is not to the immediate right or immediate left of D , also given G neither faces D nor F 
  • H/F - F/H ( one person between them ) 
  • E faces centre 
Here you get two using B and C , they can stand on the outer or inner rectangle
Case (i) When B and D on outer rectangle , In any order D on left and B on right (or ) B on left and D on right , E will always come in the inner rectangle i.e. facing outside ,this does not satisify the given condition of E to face centre. So B and D cannot stand on outer rectangle gates. 
Case (ii) When B and D on inner rectangle , in any order will satisfy all the conditions. 


1. 

( d) F is facing A 

2. 

(d) G doesn’t form the part of the group as it lies in the outer rectangle other all are in inner rectangle.

6- I
12 – D
14- T
20 – R
Rearranging this DIRT is formed ….so (d) I is the second word.

Alphabet  against 18 – P   and against letter numbered 22 have 3 alphabets in the English alphabetical order…  it can be either backward or forward direction.
In forward direction  :    P  -   -   -   T ( T already exists ) 
In backward direction :   L  -  -    -   P ( L is placed against 22)
Now  letter numbered 18 i.e. N and letter numbered 22 i.e.  L has only O in between .
So answer is one(c ) number .
