Question

12 workers can complete a piece of work in 10 days. If the number of workers are reduced 1/3 of the original number. then how many more days would be required to complete the same work?​

Answer 1

Answer:

Your answer is here:-

Step-by-step explanation:

We have been given that 12 workers can complete a piece of work in 10 days.

Also, that the number of workers is reduced to 1/3.

We know that if the workforce is reduced then the time will increase.

Now, 1/3rd of original no. of workers =1/3×12=4.

It is a case of inverse variation as we know,

So, 12 workers can complete a work in 10 days

Therefore, 4 workers can complete the same work in 12×104=1204=30 (Because work remains same)

Hence, the number of extra days that will be required by a smaller number of workforces will be =(30−10)=20.

Hope it helps you.
