Question

6 pipes can fill a tank in 3 hours. How long will 18 pipes take to fill the same tank?​

Answer 1

As per the data given in the question,

We have to determine that,

In how many time 18 pipes can fill the same tank which is filled by 6 pipes  in 3 Hours.

As we know that,

In Time and Work,

The work done by x number of workers in t days will be

$=(x\times t ) =xt \:unit$

So, work done by by 6 pipes  in 3 Hours will be $=(6\times 3) = 18\:Units$

As, 18 units of work is needed to be done by 18 pipes.

So, number of time required will be $=\frac{18}{18} = 1\:Hr$

Hence. In 1 Hr. 18 pipes can fill the same tank which is filled by 6 pipes  in 3 Hours.

Answer 2

Answer:

6 pipes can fill a tank in 3 hours. The 18 pipes take 1 hour.

Step-by-step explanation:

To find -

In how many time 18 pipes can fill the same tank which is filled by 6 pipes  in 3 Hours.

Solution-

To find the work done by 6 pipes multiply the number of pipes by the number of hours.

Work done by by 6 pipes in 3 Hours  = $6$ ×$3$

work done by by 6 pipes  in 3 Hours = 18 units

If 18 units of work should be done by 18 pipes.

∴ Time required = $\frac{18}{18}$ = $1$ hr

6 pipes can fill a tank in 3 hours. The 18 pipes take 1 hour.
