Tough and Tricky questions: Word Problems.




The figure above represents the floor plan of an art gallery that has a lobby and 18 rooms. If Lisa goes from the lobby into room A at the same time that Paul goes from the lobby into room R, and each goes through all of the rooms in succession, entering by one door and exiting by the other, which room will they be in at the same time ?

(1) Lisa spends 2x minutes in each room and Paul spends 3x minutes in each room.
(2) Lisa spends 10 minutes less time in each room than Paul does.

Kudos for a correct solution.

statement 1: sufficient
I drew a sketch on a piece of paper and then kept adding 2 minutes for each room lisa was and did the same for Paul and then saw that they would meet in room K because Lisa would be arriving there in 20 minutes and Paul would be there in 21 minutes

statement 2: insufficient
If Lisa spends 2 minutes in each room and Paul spends 12 minutes in each room, they meet in room P. If Lisa spends 14 minutes in each room and Paul spends 24 minutes in each room, they meet in room L.

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.
With this information we can identify the room where they will meet - Sufficient

Statement 2: Lisa spends 10 minutes less time in each room than Paul does.
We don't have enough information regarding the amount of time Lisa or Paul spends in each room - Insufficient

Answer A
