Analytical Reasoning Question No. 93
A driver clears all six post points—S, T, U, W, X, Y —one at a time. The sequence in which the clearing is done must conform to the following specific rules:
1. Point Y must be cleared sometime before point S and also sometime before point X.
2. Point T must be cleared sometime after point S and also sometime after point W.
3. Point U cannot be cleared immediately before or immediately after point W.
4. A point that is about to receive posts must, when it is consistent with the rules above, be cleared before a point that is not.
1. Point Y must be cleared sometime before point S and also sometime before point X.
2. Point T must be cleared sometime after point S and also sometime after point W.
3. Point U cannot be cleared immediately before or immediately after point W.
4. A point that is about to receive posts must, when it is consistent with the rules above, be cleared before a point that is not.
| Q# | Question | Options |
|---|---|---|
| 1 | If U and X alone are about to receive posts, the points can be cleared in which of the following sequences? | |
| 2 | If T and X alone are about to receive posts, which of the following must be true? | |
| 3 | If T and W alone are about to receive posts, then the points can be cleared in which of the following sequences? | |
| 4 | If W alone is about to receive posts, the points can be cleared in which of the following sequences? |
✔ Correct Answers:
1. (D) U, Y, X, W, S, T
2. (C) W is cleared third.
3. (A) Y, W, S, T, U, X
4. (E) Y, W, T, S, X, U
Explanation (short):
- Rule 1: Y before S and X.
- Rule 2: T after S and W.
- Rule 3: U not immediately before/after W.
- Rule 4: "About to receive posts" points are prioritized before non-receiving points if consistent.
Q1 (U,X receive): D satisfies Y before S/X, T after S/W, U not adjacent W.
Q2 (T,X receive): W must be third to allow T after W and S after Y etc.
Q3 (T,W receive): A works with all rules.
Q4 (W alone receive): E works correctly.
