Question
In how much time will a train running with a speed of 72
km/hr cross the second train? Statement I:  The length of the two trains is 80 metres and 100 metres respectively. Statement II:  The speed of the second train is 60 km/hr. For each of the following questions statements I and II are given. Use the data of those statements and then determine which of the following statements is necessary to answer the question:Solution
Since, we do not know the direction in which the two trains are running, we cannot answer the question. Therefore, the statement I and II are not sufficient to answer the question.
