Directions (77-79) : Study the following information carefully and answer the questions given below.

U stays 20m north of X. S stays 16m west of W. V stays 6m south of R. T stays 18m east of X. S stays 34m north of T. V stays 8m west of U.

Find the odd one out.

The correct option is T, S.

Let us analyze the positions of all the points based on the given directions step-by-step:

1. U stays 20m north of X: If we take X as the reference point (0, 0), then U is located at (0, 20).

2. T stays 18m east of X: From X(0, 0), moving 18m east places T at (18, 0).

3. S stays 34m north of T: From T(18, 0), moving 34m north places S at (18, 34).

4. S stays 16m west of W: Since S is 16m west of W, W is 16m east of S. Thus, W is located at (18 + 16, 34) = (34, 34).

5. V stays 8m west of U: From U(0, 20), moving 8m west places V at (-8, 20).

6. V stays 6m south of R: Since V is 6m south of R, R is 6m north of V. Thus, R is located at (-8, 20 + 6) = (-8, 26).

Now, let us determine the relative positions/directions of point S with respect to the first point given in each pair:

- R, S: Point R is at (-8, 26) and S is at (18, 34). S is to the North-East of R.
- V, S: Point V is at (-8, 20) and S is at (18, 34). S is to the North-East of V.
- U, S: Point U is at (0, 20) and S is at (18, 34). S is to the North-East of U.
- X, S: Point X is at (0, 0) and S is at (18, 34). S is to the North-East of X.
- T, S: Point T is at (18, 0) and S is at (18, 34). Here, S is directly to the North of T.

In all pairs except (T, S), the second point (S) lies in the North-East direction of the first point. In the pair (T, S), S lies directly North of T. Therefore, T, S is the odd one out.
