Ten persons are sitting in two parallel rows containing 5 persons in each row in such a way that there is an equal distance between adjacent persons. In the 1st row, A, B, C, D and E are sitting and all of them are facing south. In the 2nd row, J, K, L, M and N are sitting and all of them are facing north, but not necessarily in the same order. Therefore, the persons sitting in row 1 are facing the persons sitting in row 2. M sits 3 m to the left of N. Only one person sits between D and A. C is the only neighbour of B. M faces A. One person sits between L and J. Both B and L are not facing each other. Who among the following faces E?
- K
- L
- N
- J
Correct answer: K
Solution
Using the clues, A is opposite M, and the arrangement of the remaining persons in both rows becomes fixed by the distance and neighbour conditions. After placing D, B, C, E in row 1 and J, K, L, N in row 2 consistently, E is found to face K. Therefore, K is the correct answer.
