Question

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

Answer 1

40,000 workers would be required to build the Taj Mahal in 10 years.

• It is given that 20,000 workers built the Taj Mahal in 20 years.

=> Number of workers required to build the Taj Mahal in year will more than 20 as more work force would be required.

• ∴  Number of workers required to build the Taj Mahal in one year = 20,000 × 20 = 400,000

• Number of workers required to build the Taj Mahal in 10 years will less than 400,000 as the time span is more.

=> Number of men required to build the Taj Mahal in 10 years = 400,000 / 10 = 40,000

• Number of workers required to build the Taj Mahal in 10 years = 40,000
