Question

Rohan wants to build a tank in 20 days for which he hires 60 workers ,after 10 days he sees that only 30%work has been done .to speed up the process and get the tank built in stipulated times,how many workers should work on the tank​

Answer 1

200 workers.

This is because if you didn't notice 60 is double of 30 so if we were to hire 2 workers only 1 percent would be finished in 10 days  so if he were to hire 200 workers 100 percent would been done
