Three workers sort 66 boxes in a day. One of the workers is three times more productive than the second worker and twice as prod

Lelechka [254]

1 worker $=x$

2 worker $= \frac{worker1}{2}= \frac{x}{3}$

3 worker $= \frac{worker1}{3}= \frac{x}{3}$

so:

$66=x+ \frac{x}{3}+ \frac{x}{2}$

$66=x+\frac{2x}{6}+ \frac{3x}{6}$

$66*6=6x+2x+3x$

$396=11x$

$x=36$

so:

worker $1$ sorted $36$ boxes
worker $2$ sorted $18$ boxes
worker $3$ sorted $12$ boxes
