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.

Q: Answer-In how much time will a train running with a speed of 72 km/hr cross the second train? Statement I: ...

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.

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:

A If the question can be answered with the help of both the statements but not with the help of either statement itself

B If the question cannot be answered even with the help of both the statements.

C If the question can be answered with the help of statement II alone.

D If the question can be answered with the help of statement I alone.

E None of these
