II. Train ‘A’ is slower than train ‘B’.
-
- If the data in statement I alone are sufficient to answer the question, while the data in statement I alone are not sufficient to answer the question.
- If the data in statement II alone are sufficient to answer the question, while the data in statement I alone are not sufficient to answer the question
- If the data either in statement I alone or in statement II alone are sufficient to answer the question.
- If the data even in both statements I and II together are not sufficient to answer the question.
- If the data in statement I alone are sufficient to answer the question, while the data in statement I alone are not sufficient to answer the question.
Correct Option: D
As per the given all details in above question ,
Given , time = 12 seconds
From statement I , The length of both the trains together = 450 m
From statement II , Train ‘A’ is slower than train ‘B’.
Here, neither the speed of the train nor the individual length of the train is given. Hence, (d) is the correct answer.
