24 days
30 days
36 days
48 days
Correct Answer: 36 days
Solution:

Questions & Step-by-Step Solutions
If 8 workers can complete a job in 12 days, how many days will it take for 4 workers to complete the same job?
Step 1: Understand that 8 workers can finish the job in 12 days.
Step 2: Calculate how many times fewer workers there are when comparing 8 workers to 4 workers. This is done by dividing 8 by 4, which equals 2.
Step 3: Since there are 2 times fewer workers, the time taken will be 2 times longer. So, multiply the original time of 12 days by 2.
Step 4: Calculate 12 days * 2 = 24 days. This is the time it will take for 4 workers to complete the job.
Work Rate – Understanding how the number of workers and the time taken to complete a job are inversely related.
Proportionality – Applying the concept of proportionality to determine how changes in the number of workers affect the time required to complete a job.
