Question

It took 20,000 people 20 years to build Taj Mahal. Each worker works at the same rate.
How long would it have taken for 25,000 workers to build the Taj Mahal?

Answer 1

let the time that 25000workers take be X

20000:20::25000:X

product of means=product of extreme

20×25000=20000×x

500000=20000x

x=500000÷20000

x=25

the answer is 25 years
