There are some bulbs,which are numbered from 1 to 100.all the bulbs are in on conditions. The following operations are performed:- 1. Those bulbs number which are divisible by 2 are switched OFF.2. Those bulbs numbered which are divisible by 3 are switched ON (which are already OFF) and OFF bulbs are switched ON.3. Similarly bulbs numbers divisible by 4 are either switched ON or OFF depending upon there previous condition4. This procedure is adopted till 100th bulb. At the end there were how many

A cow was standing on a bridge, 5feet away from the middle of the bridge. suddenly a lightning express with 90 miles/hr was coming towards the bridge from nearest end of the cow.seeeing this the cow ran towards the express and managed to escape when the train is one feet away from the bridge. if it would have ran to opposite direction(ie away from train) it would have been hit the train one ft away from the end of the bridge. Calculate the length of bridge. speed of the cow.
A cow is standing 5 feet from the middle of the bridge .A train is at a distance of 2 times length of the bridge from direction in which cow is nearer to end of the bridge is coming at a speed of 90 miles/hour.If cow moves towards train it will be saved by 1 foot.If cow moves away from train it will be hit by three inches of cow(i)Find length of bridge(ii)Find cows speed

A Boy has taken a short cut on which there is a railway track that goes through a narrow bridge. When the boy covered 7/16th of the track in the bridge, he heard the whistle of the train. Then he ran out of that bridge, when the train came to that bridge. If he were taken actual root, he would have reached the destination on time, rather taking the shortcut and running out of that bridge. If the boy covers 4km/hr, what was the speed of the train?
