It took 20,000 workers to build the taj mahal in 20 years. how many workers would be required to build it in 10 years?

40,000 workers

Step-by-step explanation:

This question deals with simple rates proportion.

If it takes 20 years for X workers to complete a job,

if we double the amount of workers, we will take half the time.

In this case we will need 20,000 workers x 2 = 40,000 workers

greater than one
