Question

It takes 15 workers to do a certain job, who work 12 days out of 5 hours a day. In how many days will 10 workers, working 9 hours a day, finish this job?

​

Answer 1

Portuguese - Brazil

Quanto maior o número de dias, menor o número de trabalhadores necessários e menos horas por ida são necessárias.

Explanation:

`(x)/(12) = (15)/(10) . (5)/(9)\\(x)/(12) = (5)/(6)\\x = (60)/(6)\\x= 10 dias`
