Directions: Below question is followed by two statements I and II. You have to determine whether the data given in the statements are sufficient for answering the question. You should use the data and your knowledge of Mathematics to choose the best possible answer.

What is the speed of the train?

Statement I: A 360m length of the train crosses a pole in 24 seconds.

Statement II: The train crosses a platform in 30 seconds.

Option 1 : Statement I alone is sufficient to answer the question but statement II alone is not sufficient.

**Given:**

From statement I,

Length of the train = 360 m

Time taken by train to cross a pole = 24 seconds

From statement II,

Time taken by train to cross a platform = 30 seconds

**Formula Used:**

Time taken by train to cross a pole = (Length of the train)/(Speed of the train)

**Calculation:**

From statement I,

Let the speed of the train be x m/s.

Time taken by train to cross a pole = (Length of the train)/(Speed of the train)

⇒ 24 = 360/x

⇒ x = 360/24

⇒ x = 15

Hence the speed of the train = 15 m/s

And statement II alone is not sufficient to answer the question.

**∴ Statement I alone is sufficient to answer the question but statement II alone is not sufficient.**
