11. A cow was standing on a bridge, 5m away from middle of the bidge. A train was coming towards the bridge from the end nearest to the cow. Seeing this the cow ran towards the train and managed to escape when the train was 2m away from the bridge. If it had run in the 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 the bridge in metres assuming speed of train is 4 times that of the cow?
a. 32 b. 36 c. 40 d. Can't b detrmnd
12. How many six digits number can be formed using the digits 0 to 5, without repetition such that the number is divisible by the digit at its unit place.
a. 420 b. 426 c. 432 d. None
13. There is a bridge of 40m length.a cow is standing 5m away from the middle of the bridge.a train is coming from the direction nearest to the cow.if the cow runs towards the opposite direction of the train then he escapes the bridge when the train is 2m away from the bridge and if the cow runs towards the same direction as of the train then the train hits the cow 2m before the other end of the bridge.then what is the ratio of speed of the cow and the train...?

18. There is a tank which gets continuous supply from a large tank.there are 10 outlets to the tanks which can empty the tank in 2.5 hours after the tank is full.provided that the supply to the tank is open during this period.again if 6 outlet pipes are open it will take 5.5 hours to empty.how many time it will take to empty the tank if 3 pipes are open?
