Sample Question 1
Pipes Medium • Quantitative Aptitude Test
Pipe A can fill a tank in 25 minutes and Pipe B can fill it in 30 minutes. Both pipes are opened together, but Pipe A is turned off after some time and Pipe B finishes filling the tank in $16\frac{4}{5}$ minutes more. After how many minutes was Pipe A turned off?
A 5 minutes
B 6 minutes
C 7 minutes
D 8 minutes
✓ Correct Answer: B - 6 minutes
📖 Step-by-Step Solution & Conceptual Rationale:
Pipe B alone filled for $16\frac{4}{5} = \frac{84}{5}\text{ minutes}$: \[\text{Work done by B} = \frac{84}{5} \times \frac{1}{30} = \frac{84}{150} = \frac{14}{25}\] Remaining work filled by both A and B together: \[1 - \frac{14}{25} = \frac{11}{25}\] Combined filling rate of A and B: \[\frac{1}{25} + \frac{1}{30} = \frac{6 + 5}{150} = \frac{11}{150}\] Time both pipes were open together: \[\text{Time} = \frac{11/25}{11/150} = \frac{11}{25} \times \frac{150}{11} = 6\text{ minutes}\] Thus, Pipe A was turned off after 6 minutes. Thus, the correct option is (B).
