Answer 1

Answer:

24/7 hours

Step-by-step explanation:

Tap A can fill 1 tank in 8 hours

Tap A fills in 1 hour = 1/8 tank

Tap B can fill 1 tank in 4 hours.

Tap B fills in 1 hour= 1/4 tank

Tap C can empty 1 tank in 12 hours.

Tap C empties in 1 hour= 1/12 tank

Tank filled in  1 hour If all taps are opened together= 1/8+1/4-1/12

                                                              =>3+6-2/24

                                                              =>7/24

hours takenn to fill tank = 24/7 hours
