Multiple choice

Directions: This data sufficiency problem consists of a question and two statements, labelled (A) and (B), in which certain data is given. You have to decide whether the data given in the statements is sufficient for answering the question. Mark your answer accordingly. A marathon runner running along a prescribed route passes through neighbourhoods J, K, L, M and not necessarily in that order. How long does it take to run from J to M? (A) The runner, at the average runs for 8 km per hour on the route from J to M. (B) M is 4 km from K and 12 km from L, but J is 15 km from K.

  1. The question can be solved using any one of the statements.

  2. The question can be solved using either of the statements.

  3. The question cannot be solved using the given statements.

  4. The question can be solved using both but not either alone.

  5. None of these

C Correct answer
Explanation

Statement A gives speed but not distance. Statement B gives distances between some points but not the total distance or the specific route order between J and M. Neither statement alone or combined provides enough information to determine the time taken.

AI explanation

To find the time, we need the distance from J to M and the runner's speed. Statement (A) provides the speed but no distance. Statement (B) provides distances between M, K, L, and J, but without knowing the exact order of the neighborhoods or the route layout, we cannot determine the distance from J to M. The question cannot be solved using the given statements.
