B and A must not have anybody adjacent to their rooms. There is only an empty room between A and F. C is adjacent to both G and F. E is next to the room at the beginning. |
A) G
B) C
C) No body
D) F
Correct Answer: A
Solution :
G is in the third room. From the question, we get following information: (i) (ii) (iii) (iv) GFC or FCG We can't place, A, F and C at the end of the row. Also, B and G cannot occupy room no. 1. So, first room will be empty and B or G can occupy last room. If G is in last room, the arrangement will be given below: But, B cannot occupy room no.-3 or room-4 because it does not satisfy condition (ii). Hence, B is in last room. Again there are two possibilities. This arrangement violates condition (ii). This is right arrangement.You need to login to perform this action.
