Performance 81586

The performance of three lathes can be expressed by the ratio 3:5:8. The most powerful lathe produces 136 shafts per shift. How many shafts did each of the remaining lathes make per shift?

Correct answer:

a =  51
b =  85

Step-by-step explanation:

$$\begin{gathered} 3<5<8 \\ a<b<c \\ c=136 \\ a:b:c=3:5:8=3x:5x:8x \\ x=c/8=136/8=17 \\ a=3\cdot x=3\cdot 17=51 \end{gathered}$$

$b=5\cdot x=5\cdot 17=85$
