Question

Ten pipes through which water flows at the same rate can fill a tank in 28 minutes.If three pipes go out of order how long will the remaining pipes take to fill the tank

Answer 1

Given,

Ten pipes can fill the tank in 28 minutes.

To find,

If three pipes go out of order then the total time needed to fill the tank.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

Here, we have to apply the normal Arithmetic process.

Number of remaining pipes = (10-3) = 7

Now,

10 pipes can fill the tank in = 28 minutes

1 pipe can fill the tank in = 28×10 minutes

7 pipes can fill the tank in = (28×10)/7 = 40 minutes

Hence, it will take 40 minutes to fill the tanks by the remaining pipes

Answer 2

Answer:

1 pipe can fill the tank in=10×28min

7 pipe can fill the tankin=10×28/7min

= 40 min
