Explanation
Setup:
Six products (U, V, W, X, Y, and Z) are to be placed on six stalls in the “Pakistan Cultural Exhibition,” numbered 1 through 6 from left to right. The following conditions apply:
- U cannot be immediately to the left or immediately to the right of V.
- W must be immediately to the left of X.
- Z cannot be on stall 6
Which of the following products CANNOT be placed on stall 1?
Options:
A. U
B. V
C. W
D. X
Correct Answer: C
Reason: Since W must be immediately to the left of X, W cannot be placed on stall 1 because there would be no space for X on the left.
If X is placed on stall 3, W must be placed on which stall?
Options:
A. 2
B. 4
C. 5
D. 6
Correct Answer: A
Reason: W must be immediately to the left of X, so if X is on stall 3, W must be on stall 2.
If U is placed on stall 5, which of the following products must be placed on stall 6?
Options:
A. V
B. W
C. X
D. Y
Correct Answer: D
Reason: Z cannot be on stall 6 (as per the rules). W and X must be adjacent, so they cannot fit in 5 and 6. Y is the only option left for stall 6.
If Z is placed on stall 3, immediately to the right of X, which of the following products must be placed on stall 5?
Options:
A. V
B. W
C. X
D. Y
Correct Answer: D
Reason:Since Z is in stall 3, and it's immediately to the right of X, this means:
X must be in stall 2
W must be in stall 1 (since W is to the left of X).
Now, stalls 4, 5, and 6 remain for U, V, and Y.
If U is placed in stall 5, V cannot be adjacent (i.e., stall 4 or 6).
This means Y must be placed on stall 5 to allow V and U to be separated.
