Tap ‘A’ can fill an empty water tank in 12 hours while tap ‘B’

1.	Tap ‘A’ can fill an empty water tank in 12 hours while tap ‘B’ can fill it 4 in 15 hours. If both the taps are opened together and after 3 hours,tap ‘B’ is closed then find in what time tap ‘A’ will fill the remaining tank?
Answer» Answer: the tank is FULL now Step-by-step explanation: A takes 12 B takes 4 when we DIVIDE each other means 12÷4 =3 hours it means 1h of B =3h of A And if both are OPEN for 3h then we have to understand that if B takes only 4h and 3h of A TAP = 1h of B tap then 3h of B + 3h of A 3h of B + 1h of B (because 3h of A tap = 1h of B tap) 3h + 1h = 4h of B tap then the tank is full THANKYOU

Answer:

the tank is FULL now

Step-by-step explanation:

A takes 12

B takes 4

when we DIVIDE each other means

12÷4 =3 hours

it means 1h of B =3h of A

And if both are OPEN for 3h

then we have to understand that if B takes only 4h and 3h of A TAP = 1h of B tap then

3h of B + 3h of A

3h of B + 1h of B (because 3h of A tap = 1h of B tap)

3h + 1h = 4h of B tap then the tank is full
