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.
Speed =
The correct answer is (E).| Ambika said: (Dec 25, 2010) | |
| Ambika 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. | |

| 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. | |

| 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? |

| x/9 = x+240/24. 24x = 9x + 2160. 15x = 2160. x = 144. |
