SECTION I - 8 questions.Series.

1. Interchange of letters in a word and the adjacent letters are also to be changed. given letters series 

    like [also few condotions]
     AAABBB=
    ABABAB=
    LET QUESTION IS ABBAAB
    If we apply 25 on this it means we have to interchange the letters at positions 2 and 5, and we have 

    to change the adjacent letters 2 and 5 from A to B and B to A.That is q's A B B A A B after Step 1 i.e 

    interchange 2 and 5.now change adjacent elements of 2 and 5...finally answer becomes
     Ans: B A A B B A
     Hint: As per question papers 5 questions above like but numberschange.
     REMAINING 3 QUESTIONS:
   6. To get AAABBD from BBBAAA what ot apply:-
      a) 25 b) 34 c)25 & 34 d) noneSECTION II
   1. Given the function f(n a b c ) = ac if n=1
      f(n a b c) = f( n-1 a b c) + f( 1 a b c) + f( n-1 b a c )
     if n > 1
     f( 2) = ?
     Ans: f( 2 a c b ) = ab + ac + bc.

2. similar question in functions.

3. [ based on function in 1.] f( 4 a b c ) the number of terms is...?
    Ans: f( 4 a b c ) = f( 3 a c b ) + f( 1 a b c ) + f( 3 b a c ) etc.
    = 5ab + 5ac + 5bc.
4. f( 5 a b c ) = ?

  SECTION III
  Permutations and Combinations.
  8 questions.
  1. r = number of flags;
  n = number of poles;
  Any number of flags can be accommodated on any single pole.
  i) r=5,n=5 The no. of ways the flags can be arranged ?
  ii) to iv) are based on this.

6. r= 5 n = 3 . If first pole has 2 flags ,third pole has 1 flag
    how many ways the remaining can be arranged?

7.& 8. same as above.
    SECTION IV
    Question consising of figures consist of 4 small squares and every square having an arrow pointing in   

    one Direction. GRE test of reasoning.
    hint: What is the next sequence if we tilt the figure by 90 degrees like that( clockwise and mirror 

    images ? ).
