Q21.In National Refinery, A is B's immediate superior, C is superior to D, B works under E, and F is superior to C. Which statement cannot be true?

Medium
A B is superior to C
B A is superior of F
C E is superior of F
D B works under D
Logical Statements PPSC

Correct Answer: D

Since B works under E, and A is the superior of B, B has a defined hierarchy. Saying B works under D would contradict other hierarchical constraints.

Q22.In a class of 60 males and 35 females, 80% failed in Chemistry and 30% failed in English. Which of the following must be true?

Medium
A Only females failed
B No male failed
C Only males failed
D Both male and female students failed
Logical Statements PPSC

Correct Answer: D

Since 80% failed Chemistry, the absolute number of failures (76) exceeds both the total male (60) and female (35) populations individually, so both genders must have some failures.

Q25.A man is facing west. He turned 45 degrees in the clockwise direction, then another 180 degrees in the same direction, and then 270 degrees in the anticlockwise direction. Which direction is he facing now?

Medium
A South
B North-West
C West
D South-West
Inference PPSC

Correct Answer: D

Tracking angles from West (270°): 1) Clockwise 45°: 270 + 45 = 315° (NW). 2) Clockwise 180°: 315 + 180 = 495° (which is 495 - 360 = 135°, SE). 3) Anticlockwise 270°: 135 - 270 = -135° (which is 360 - 135 = 225°, SW). Thus, he faces South-West.
