A doctor is to visit a patient. From the past experience, it is known that the probabilities that he will come by train, bus, scooter or by other means of transport are respectively (3)/(10),(1)/(5),(1)/(10) and (2)/(5) . The probabilities that he will be late are (1)/(4),(1)/(3) and (1)/(12) , is he comes by train, bus and scooter respectively, but if he comes by other means of transport, then he willnot be late. When he arrives, he is late. The the probability that he comes by train is

A man can swim in still water at a speed of 6 kmph and he has to cross the river and reach just opposite point on the other bank. If the river is flowing at a speed of 3 kmph, and the width of the river is 2 km, the time taken to cross the river is (in hours)
