How do teachers connect with students in virtual classrooms? Is it easier or more complicated?

The pandemic raised two concerns for the student and teaching community: 1. How will learning continue? 2. What would happen to classroom

Let, the total volume of the tank be x litres.

In case of first tap,

in 12 hrs, it supplies x litres of water

So, in 1 hr it supplies x/12 litres of water

And, in case of 2nd tap,

in 10 hrs, it removes x/2 litres of water

In 1 hr, it removes x/20 litres of water

Therefore after 1 hr the ultimate amount of water remaining in the tank, when both the taps are on..

=X/12-X/20.

=x/30

Let the required number of hours be Y

Then (x/30)*Y=X

Y=30 hrs (ans)
