Mr. Beans visited a magic shop and bought some magical marbles of different colours
along with other magical items. While returning home whenever he saw a coloured light, he
took out marbles of similar colours and counted them. So he counted the pink coloured
marbles and found that he has bought 25 of them. Then he counted 14 green marbles and then
21 yellow marbles. He later counted 30 purple coloured marbles with him. But when he
reached a crossing, he looked at a red light and started counting red marbles and found that he
had bought 23 Red marbles. As soon as he finished counting, it started raining heavily and by
the time he reached home he was drenched. After reaching home he found that the red, green
and yellow marbles had magically changed colours and became white, while other marbles
were unchanged. It will take 1 day to regain its colours, but he needs to give atleast one pair
of marbles to his wife now. So how many white marbles must be choose and give to his wife

idiosyncratic collections in French impressionist art. Dr. Barnes who put together this
collection has insisted that the paintings be hung in a particular manner specified by him at a
museum designed by the French architect Paul Philippe Cret who also designed the Rodin
Museum. The museum has, say, seven galleries – Eugene Boudin, Cassatt, Boudin, Forain,
Gonzales, Manet and Monet. Visitors reach the main Eugene Boudin by an elevator, and they
can enter and leave the exhibition only through Eugene Boudin gallery. Once inside, visitors
are free to move as they choose. The following list includes all of the doorways that connect
the seven galleries: There is a doorway between Eugene Boudin and Cassatt, a doorway
between Eugene BoudinandBoudin, and a doorway between Eugene Boudin and Gonzales
galleries. There is a doorway between Cassatt and Boudin galleries. There is a doorway
between Gonzales and Forain and a doorway between Gonzales and Manet galleries. There is
a doorway between Manet and Monet galleries. Which of the following rooms CANNOT be
