REMAINING 3 QUESTIONS:
6. To get AAABBD from BBBAAA what ot apply:-
a) 25 b) 34 c)25 & 34 d) none
SECTION 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 ) = ?
