I have discussed various problems for bank po level. These could be useful for those who are preparing for CAT like exams also.

A train whistles when it is at a certain distance from a tunnel XY. A cat is sitting inside the tunnel at a distance of 5/12 of the length of the tunnel as measured from the entrance X. If the cat runs towards the entrance, the train catches it at point X. And, if it runs towards the exit, then the train catches it at the point Y. What is the ratio of the speed of the train to that of the cat?

A train crosses two girls walking opposite to it in 36 and 30 seconds respectively. What is the length of the train if the speeds of the girls are 3 and 6 km/h?

Two boys A and B are running in the same direction at 6 km/h and 3 km/h, respectively. A is behind and B is some distance ahead of him. A train travelling at 54 km/h is coming from behind and the three of them come in such a position where B is at the head and A at the tail of the train. When the boys meet, the tail of the train is 320 meters away. What is the length of the train?
