Answer:Time taken to fill the tank when both the taps open be xhrs

In 1hour the tank is filled when both the taps open=1/x

In 10hrs the tank is filled.

So, in 1hr the tank filled=1/10

In 15hrs the tank is emptied.

So, in 1hr the tank emptied=1/15

A.T.Q

1/X = 1/10 – 1/15

= (3-2)/30

=1/30

So x=30hrs
