                 Pattern = 5 * 8 =40   

 1…..A question will be givem with six characters like  AAABBB

         16 MEANS YOU HAVE TO INTERCHANGE Ist character with VI th one and then change the         

                                      BBABAA

                      25=>       AAABBB

                                     ABABAB

                                    BBBAAA

                      34 =>      AAABBB

                                     AABABB

                                     ABBAAB

                8 QUESTIONSA MODEL   

(I.                   apply  25 &34  successively)

(II.                 Apply 34 & 16 successively)

III.               Apply 16 &16 successively)

(IV.               Apply 25&25 successively)                               etc…….

Another  question …

I.                     BAABBA CAME FROM APPLICATION OF

Choice 1.                34 & 25 succesively.

Choice 2.                25 & 25 succesively.

Choice 3.                34 & 34 succesively.

                              Answer and hint

1.        If  two conditions are being applied simultaneously the you will get same answer.e.g….suppose 

       AAABBB…Apply 34& 34 then the result will be AAABBB

 
  2.                F(n,a,b,c)       =     AC if n=1

                    F(n,A,B,C)     =   F(n-1,A,C,B)+ F(1,A,B,C) + F(n-1,B,A,C)

     This is the question.

i.                     find  F(2,B,A,C) = F( 1,b,c,a)+ F(1,b,a,c)+F(1,a,b,c) =ba+bc+ac

ii.                   Find F(2,C,A,B) = F( 1, c,b, a)+ F(1, c,a,b)+F(1,a,c,b) =ca+cb+ab

(one imp. Point ca not = bc); (ca+cb+ab) is not = (ab+cb+ca)

iii.                  F(4,a,b,c) = ?= F(3,a,c,b) +F(1,a,b,c) +F(3,b,a,c)

F(3,a,c,b) =  F(2,a,b,c) + F(1,a,c,b) +F(2,c,a,b)

                F(2,a,b,c) =  F(1,a,c,b) +F(1,a,b,c) +F(1,b,a,c)

                So ab+Ac+bc = 3.

f(2,a,b,c) =3 ;f (3,a,b,c) = 3+1+3 = 7, f(4,a,bc,)= 7+1+7=15

Like this find f(5,a,b,c)= ?=( ans =31 pl. check)

Like this find f(3,a,b,c) =?

3……                  N= no of poles

                R= No of flags

                If N=5 and R=4

What are the possible ways the flag can be tag to the poll. 1^st pole = 2,3,4

Ans=> 5*5*5*5 = 5to the power 4 = 625

                Most probably choice (D)

 
  If N=3 and  R=3  and if the flag are identical what rae the diff. Ways flags can be tagged .

 
   Ans+10 ( Please cross check)

   If N=3 and R=3 and if flags and poles are identical

   Ans => 3

 
 If N=4  and R=3 and if both flag and poles are identical

 
  Ans=> 3

 
 If N= 5 and R=5 Two flags tied in the first pole one flag tied in the third pole what are theways that the 

   remaining flags can be tied.

       Ans => 3*3*3
