Question

One tap can fill a cistern in 5 hours and another in 6 hours. If both the taps start, filling the cistern simultaneously then in how much time the cistern will be filing​

Answer 1

Step-by-step explanation:

One tap can fill a cistern in 5 hours

2nd tap can fill a cistern in 6 hours

they both fill in one hour .

$\frac{1}{5} + \frac{1}{6} \\ \frac{6 + 5}{30} \\ \frac{11}{30}$

therefore the both tap can fill the cistern

1÷11/30

30/11 hr.
