Question

() A pipe takes 6 hours for filling 42 containers. How many containers will it fill in 42 hours?
​

Answer 1

Answer:

A machine takes 6 hours in filling 48 containers

The machine takes 1 hour in filling 8 containers

The machine takes 48 hour in filling 8 × 48 containers

= 384 containers.

Answer 2

Answer:

294 containers will be filled up in 42 hours.

Step-by-step explanation:

We have been given here a sum based on the unitary method where we have to calculate the value of the containers that the respective pipe will fill in 42 hours. We have been mentioned here that in 6 hours it can fill up to 42 containers, therefore we have:

No. of containers filled in 6 hours = 42

∴ No. of containers filled in 1 hour = 42 ÷ 6 = 7

∴ No. of containers filled in 42 hours = 7 × 42 = 294

Hence in 42 hours, 294 containers will be completely filled up.
