Correct!
Not quite. The correct answer is highlighted.
Correct answer to question 75 (Arithmetic Reasoning): 4 hours

More pumps means less time, so the relationship is inverse. The job takes 8 x 6 = 48 pump-hours, and 48 divided by 12 pumps gives 4 hours. Answering 9 treats the relationship as direct.
