Question

10 tap can fill a water tank in 30 minutes. how many minutes can will 15 tap take to fill the same tank ​

Answer 1

Answer:

10 Min

Step-by-step explanation:

Correct answer:

Tap A can fill the tank in 30 minutes. Therefore, it fills 130th of the tank every minute.

Tap B can fill the tank in 60 minutes. Therefore, it fills 160th of the tank every minute.

Together, the two taps will fill 130+160=2+160=360=120th of the tank every minute.

Therefore, when both the taps are opened simultaneously, they will fill the tank in 20 minutes. As the tank is already half full, they need to fill only half the tank.

Therefore, the tank will overflow 10 minutes after both the taps are opened

Answer 2

Answer:

20 minutes

Step-by-step explanation:

Let the time by x

∴  10 x 30 = x x 15

⇒ 300 = 15x

⇒ x  = 300/15

⇒ x  = 20

Hence, the time taken by 15 taps to fill the same tank is 20 minutes
