Question

Pipe A can fill a tank in 5 hours. pipe B can fill in 10 hours and pipe C can fill in 30 hours. if all the pipes are opened, then in how many hours will the tank be filled​

Answer 1

Answer:

Its answer is 3 hours to fill the tank

Answer 2

Answer:

3 hour

Step-by-step explanation:

Pipe A = 5 hours

Pipe B = 10 hours

Pipe C = 30 hours

LCM(5,10,30) = 30

Efficiency of pipe A = 6

Efficiency of pipe B = 3

Efficiency of pipe C = 1

when all the pipes are opened,

time taken = 30

6 + 3 + 1

= 30 hour

10

= 3 hour
