A sample question from this test
A tank holds 540 litres. An inlet pipe fills it at 30 litres per minute while an outlet pipe drains it at 10 litres per minute. If both are open, in how many minutes will the empty tank be full?
- 27
- 28
- 34
- 37
Answer: A. 27. Net filling rate = 30 − 10 = 20 litres per minute. Time = 540 ÷ 20 = 27 minutes.
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 leans hard, with multi-step questions, so treat it as a stretch: attempt the questions you can see a method for first and return to the rest. At 40 questions in 60 minutes, you have about 90 seconds per question on average. After you submit, review every wrong or guessed answer using the explanations.
