Question 1018430: Problem:
It takes $1200$ workers $8$ years to build $3$ ziggurats. How many years would it take $100$ workers to build $1$ ziggurat? (Assume all workers work at the same constant rate.)

You can put this solution on YOUR website!
From the facts here, it takes 1200x8 = 9600 worker-years to build 3 ziggurats.
That means it takes 9600/3 = 3200 worker-years to build just one.
100 workers need 32 years to make the 3200 worker-years to build 1 ziggurat.
