A sample question from this test
A tank holds 750 litres. An inlet pipe fills it at 65 litres per minute while an outlet pipe drains it at 35 litres per minute. If both are open, in how many minutes will the empty tank be full?
- 15
- 25
- 28
- 35
Answer: B. 25. Net filling rate = 65 − 35 = 30 litres per minute. Time = 750 ÷ 30 = 25 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 easy, so use it to confirm that you can solve the basic pattern accurately before you move to harder sets. At 20 questions in 30 minutes, you have about 90 seconds per question on average. After you submit, review every wrong or guessed answer using the explanations.
