Directions: Study the given information carefully to answer the given question.

M, N, O, P, Q, R and Sare seven people live on seven different floors of a building but not necessarily in the same order. The lower most floor of the building is numbered 1, the one above that is numbered 2 and so on till the topmost floor is numbered 7. Each one of them have different income i.e. 3500, 15000, 7500, 9000,11000, 13500 and 5000. (But not necessarily in the same order.)

M lives on an odd-numbered floor but not on the floor numbered 3. The one who has income of 11000 lives immediately above M. Only two people live between M and the one who has income of 7500.

The one who has income of 15000 lives on one of the odd-numbered floors above P. Only three people live between O and the one who has income of 15000. The one who has income of 7500 livesimmediately above O. R earns 4000 more than Q. The one who has income of 3500 lives immediately above the one who has income of 5000.Only one person lives between N and Q. N lives on one of the floors above Q. Neither O nor M has income of 9000. Q does not has income of 7500.

If all the people are made to sit in alphabetical order from top to bottom, the positions of how many people will remain unchanged.

Direction: Study the information given below carefully and answer the questions that follow.

There are 10 members in the family who are sitting at some distance from each other in a park. N is 4 m in the west of M, who is 5 m in the north of O. Q is 12 m in the west of R. T is 3 m in the west of S, which is 12 m in the south of R. O is 6 m in the east of V, which is 2 m in the north of P, which is 8 m in the west of U. T is 1 m in the south of U.

In which direction is U with respect to M?
