Answer 1

Answer:

Hence both tap can fill tank in 12 hours

Step-by-step explanation:

Tap A can fill 1 tank in 4 hours

Tap A can fill in 1 hour = 1/4 tank

Tap B can empty 1 tank in 6 hours

Tap B can empty in 1 hour = 1/6 tank

Both tap if operated at same time will fill tank in 1 hour = ( 1/4–1/6) tank

= 3–2/12

= 1/12
