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 numbers change. 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 ? ). SECTION V In this section first part of compound word is given. Select meaning of the second part from the
