Given:
(5 Men)(6 hours/day) can produce (10 toys/6 days)
Simplifying...
(30 man-hours/day)(6 days/10 toys) = 180 man-hours required to produce 10 toys
or....
18 man-hours to produce 1 toy


Therefore, assuming the men work at a constant rate of (18 man-hours / 1 toy):
(18 man-hours / 1 toy)(16 toys / 1)(1 / 12 men)(1 day/8 hours) = 3 days

(If you're having trouble following along, ensure that you properly label your ratios and proceed to cancel out the labels to arrive at "days")
