Predetermined 8094

Lumberjacks cut down a predetermined number of trees over the course of three days. On the first day, they cut down a quarter of the trees; on the second day, they cut down 6 more trees than on the first day; on the third day, they cut down 6 more trees than on the second day. How many trees did they cut down on the third day?

Correct answer:

c =  5/12

Step-by-step explanation:

$$\begin{gathered} n/4+(n/4+6)+(n/4+6+6)=n \\ n=72 \\ n=\frac{72}{1}=72 \\ n=72 \\ {c}_1=n/4+6+6=72/4+6+6=30 \\ c=c_1/n=30/72=\frac{5}{12}=0.4167 \end{gathered}$$
