Question

Three taps A, B and C can fill an overhead tank in 6 hours, 8 hours and 12 hours respectively. How long would the three taps take to fill the empty tank, if all of them are 16. opened together?​

Answer 1

Answer:

So the three taps will take 8/3 = 2 (2/3) hours to fill the tank

Step-by-step explanation:

A fills in 6 hrs

B fills in 8 hrs

C fills in 12 hrs

In 1 hr, A can fill 1/6

           B can fill 1/8

           C can fill 1/12

So together, in hr, A+B+C can fill = 1/6 + 1/8 + 1/12 = 18/48 = 3/8

So the three taps will take 8/3 = 2 (2/3) hours to fill the tank
