Directions : Below is given a question followed by two statements numbered I and II. The question may be or may be not answered with the help of these statements. You have to decide If these statements are sufficient to answer the the questions. Give answer
What is the speed of train A?
Statements: I. It crosses a pole in 25 seconds.
II. The train is 200 m long.

Options

A. if only statement I is sufficient to answer the question but statement II is not,
B. If only statement II is sufficient to answer the question but statement I is not,
C. if both statements I and II are together sufficient to answer the questions although neither statement suffices by itself,
D. if statement I and statement II are sufficient to answer the questions independently and separately,

Answer

C

Explanation

From the two statements together, we can find that the answer to the question is 200 + 5 = 40 m per second. We can safely assume that a pole has no length and, hence, in passing a pole a train only covers a distance which is equal to its own length.
