Answer: Total time taken by them would be 60 minutes = 1 hour before the tank overflows.
Step-by-step explanation:
Since we have given that
Time taken by an inlet pipe =10 minutes
Time taken by a drain = 12 minutes
So, if both are open together,
Total work done by them would be
[tex]\dfrac{1}{10}-\dfrac{1}{12}\\\\=\dfrac{6-5}{60}\\\\=\dfrac{1}{60}[/tex]
So, total time taken by them would be 60 minutes = 1 hour before the tank overflows.
