Statement 1: Lisa spends 2x minutes in each room and Paul spends 3x minutes in each room.
We can deduct that by the time Lisa passes from 3 rooms, Paul can pass through only 2 rooms.
This way we get a movementpattern , hence we can find the room in which they meet
Sufficient
Statement 2: Lisa spends 10 minutes less time in each room than Paul does.
lets paul takes 200 min, Lisa takes 190 min
or, paul takes 20 min and Lisa takes 10 min.
hence the movement pattern in both cases would be different.
