Discussion :: Problems on Trains - Data Sufficiency 1 (Q.No.3)
Each of the questions given below consists of a statement and / or a question and two statements numbered I and II given below it. You have to decide whether the data provided in the statement(s) is / are sufficient to answer the given question. Read the both statements and
- Give answer (A) if the data in Statement I alone are sufficient to answer the question, while the data in Statement II alone are not sufficient to answer the question.
- Give answer (B) 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.
- Give answer (C) if the data either in Statement I or in Statement II alone are sufficient to answer the question.
- Give answer (D) if the data even in both Statements I and II together are not sufficient to answer the question.
- Give answer(E) if the data in both Statements I and II together are necessary to answer the question.

Please any help me; I can't understand how it is possible , because here they didn't give any comment about speed . How can we equate both speeds (Man &Train). I think option D is correct. Anybody can understood please explain to me.

|Here same train is crossing both man n d platform so d speed ll b same in both d cases so optn E is correct|

|Speed of man is not mentioned. What if he is also moving with some speed. So answer should be D.|

|Please give some instruction about train problems?|

|Can you please explain what the answer to the equation is I chose option B on the premise that the length of the train is 10 m.
How would we solve the equation please?

|The speed of the train is given but nothing is mentioned about the speed of the man.
How can it be solved unless condition about the man is given?

|It's possible? I can't get it. Anyone else explain it.|

|Train is passing a man.
Obviously the length of train will be the same as the required distance to pass that man as man has no length.
9 sec to pass the man (given).
24 sec to travel 240 m (given).
So, speed = 240/24 = 10 m/s.
Hence, Length of train = Distance travelled in 9s = 9*10 = 90 m.

|Answer should be D. No reason to assume the same speed of the train in both cases.|

|How 1st statement is true? Explain.|
|Sana said: (Dec 15, 2018)|
|Man is stationary & speed of the train is same for passing both man and platform. Thatswhy we can equate the two equations and get the length. It comes to be 144 meters.|
|Atul said: (Feb 3, 2019)|
|How can we say the train crossing the man and the platform is same. Also, the speed is also same. If nothing is given how option E is correct. Please specify in the question if any assumption is to be made or not.|

|How can we say that the speed of train to cross man and platform is same?
Please anyone explain?
