A sample question from this test
Two pipes can fill a tank in 12 hours when opened together. One of them alone can fill it in 16 hours. In how many hours can the other pipe alone fill the tank?
- 46
- 48
- 50
- 58
Answer: B. 48. Other pipe's rate = 1/12 − 1/16 = 1/48. So it alone fills the tank in 48 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.
