Six families A,B,C,D,E & F are living in houses in a row,B has F and D as neighbours,E has A & C as neighbours.A does not live next to either F or D,C does not live next to D.Who are F's next door neighbours?

• A. B & E
• B. B & D
• C. B & C
• D. Only B

Answer 1

The correct option is C B & C

As B has neighbours F and D, so B will be between F and D.

The sequence can be formed is either F B D or D B F.

E has the neighbour A & C and the sequence of house formed is either A E C or C E A.

Since, A does not live next to either F or D. Also C does not live next to D.

So, A E C F B D is one possible sequence of houses arranged in a row.

And D B F C E A is another possible sequence of houses arranged in a row.

In both the sequences F's neighbours are B & C.

Hence, option C is correct.
