Job problem: 10 men can make 20 toys in 12 days working 12 hours a day.Then, in how many days can 24 persons make 32 toys working 16 hours a day?

Correct answer:

t =  6

Step-by-step explanation:

$$\begin{gathered} h=20/(10\cdot 12\cdot 12)=\frac{1}{72}\doteq 0.0139 \\ t\cdot 24\cdot 16\cdot h=32 \\ t=\frac{32}{24\cdot 16\cdot h}=\frac{32}{24\cdot 16\cdot 0.0139}=6 \end{gathered}$$
