If 10 men do a piece of work in 92 days how may days will it take 20 men to do it
+66 | 10 men | 92 days |
| 20 men | x = 46 days |
x = (92*10)/20 = 46 days

Let m = number of men
Let d = number of days
Let w = the work
m*d = w
We are given 10 men can do the work in 92 days.... so
10*92 = w. (1)
20 men = 20 * d = w. (2)
(1) = (2)
10*92 = 20*d
92 = 2 * d
d = 46
Overkill but whatever.
