c. how many members are there between a and e

Answer 1

b,d,c,f there will be 4 members between a and e

Answer 2

Answer:

$\setlength{\unitlength}{3mm}\begin{picture}(8,2)\thicklines\put(1.4,1.8){\vector(3,4){5}}\put(1.4,1.8){\vector( - 3, - 4){5}}\put(2,1.5){\vector(2,0){7.5}}\put(2.1,1.5){\vector( - 2,0){9}}\put(1.2,1.5){\vector( - 1,1){6.2}}\put(1.2,1.5){\vector(1, - 1){6.2}}\put( - 5, -6){\sf F}\put(7,9){\sf B}\put( - 8.5,1){\sf C}\put(10,1){\sf D}\put(-6,8){\sf E}\put(8,-6){\sf A}\end{picture}$

⠀⠀⠀⠀$\rule{150}{2}$

⇒ A is between D and F

⠀

Put D and F at any two points with one gap in between for A. Now Three Places are Occupied.

⠀⠀⠀⠀$\rule{150}{1.2}$

⇒ C is opposite to D

⠀

C will sit on exact opposite of D. Now Two Places are Left.

⠀⠀⠀⠀$\rule{150}{1.2}$

⇒ D and E are not on neighbouring chairs

⠀

E can't sit nearby D, Hence it will sit beside C. And at the Left Place B will sit.
