Arnab organized a seminar. He invited 3 female guests A, B, and C. He also called 3 male guests P, Q, and R. But by mistake he arranged 9 chairs in a single row and numbered them 1-9 from left to right.
- None of the females are sitting next to each other
- A and B are not sitting next to any other guests
- C is next to Q and R
- B, P and R are not at the end of the row
- P is sitting next to a chair at the end of the row
- There is only one vacant chair between B and R
