A sample question from this test
A pipe can fill a tank in 20 hours, but a leak at the bottom can empty the full tank in 40 hours. If the pipe is opened with the leak, in how many hours will the empty tank be filled?
- 80
- 39
- 40
- 43
Answer: C. 40. Net part filled in 1 hour = 1/20 − 1/40 = 1/40. So the tank is filled in 40 hours.
How to approach this test
Treat filling pipes as positive rates and emptying pipes or leaks as negative rates, then divide the capacity by the net rate.
This set mixes straightforward questions with a few that need an extra step, so it works well as a checkpoint once the basics are comfortable. At 30 questions in 45 minutes, you have about 90 seconds per question on average. After you submit, review every wrong or guessed answer using the explanations.
