A cow was standing on a bridge, 5m away from the middle of the bridge. A train was coming towards the bridge from the end nearest to the cow. Seeing this cow ran towards the train and managed to escape when the train was 2m away from the bridge. If it had run in opposite direction(i.e away from the train) it would have been hit by the train 2m before the end of the bridge. What is the length of bridge in meters assuming speed of the train is 4 times that of the cow.	Options:  A) 32  B) 36  C) 40  D) 44  E) 50
Explanation :   Explation:   Let length of bridge is X   then middle of bridge is X/2.   and Cow is standing at X/2-5 from the end so   After seeing the train it would run opposite direction and cover distance of X/2-5 when the train is 2m away from other side.   So, the bridge from one side to cow is {(X/2-5)+(X/2-5)}=X-10   so remaining distance is 10m   the cow is hit before 2m i.e cow covers 8m and train will cover 32 m.   32nswer : 32
