Multiple choice

Directions: The following problem consists of a question and two statements labelled as (1) and (2). You have to decide whether the data given in the statements is sufficient to answer the question. Mark the appropriate choice from (1) to (4). Can we find the time after which two persons A and B, moving towards each other will meet if (1) distance between the two is known (2) A's speed is twice that of B

  1. both statements (1) and (2) together are not sufficient.

  2. both statements (1) and (2) taken together are sufficient, but neither statement (1) alone nor statement (2) alone is sufficient.

  3. statement (1) alone is sufficient, but statement (2) alone is not sufficient.

  4. statement (2) alone is sufficient, but statement (1) alone is not sufficient.

AI explanation

To find the time it takes for two people to meet, you must know the total distance between them and the sum of their individual speeds. Statement (1) provides the distance but lacks any speed values, while statement (2) only provides a ratio of their speeds without giving the exact speeds. Therefore, even when using both statements together, the actual speeds remain unknown, so the data is not sufficient to calculate the meeting time.
