.Six persons A,B,C,D,E & F went to solider cinema. There are six consecutive seats. A sits in
one of the seats
followed by B, followed by C and soon. If a taken one of the six seats , then B should sit
adjacent to A. C
should sit adjacent A or B. D should sit adjacent to A, B,or C and soon. How many
possibilities are there?

• A and B should be adjacent , so A and B taken together. 2!
  C should be adjacent to A or B. So (AB) and C taken together. 2!2!
  D should be adjacent to A,B or C. SO ((AB)C) and D taken together. 2!2!2!
  E should be adjacent to A,B,C or D. SO (((AB)C)D) and E taken together. 2!2!2!2!
  F should be adjacent to A,B,C or D. SO ((((AB)C)D)E) and F taken together. 2!2!2!2!2! = 32 ways

• A can sit in 6ways first.B can sit 2 ways if A sits in other than extreme ends,C has 2 ways and so on
  Hence 6*2*2*2*2*1=196ways
  If a sits in one of the extreme ends A can sit in 2 ways and the remaining persons can sit in 1 ways each hence 2 ways
  so total 198 ways
