Step-by-step explanation:
let x be the number of days
12m * 15d = 10m * x
(12m = 12 men , 15d =15days , 10m = 10 men )
12 * 15 = 10 * x
x = 180 / 10= 18 days.
Hope this helps you.

Answer:
12/10 = 1.2
Therefore 12 men is 1.2 times as efficient as 10 men.
Thus divide 15 by 1.2.
15/1.2. = 12.5 Days
The reason we divide is:
Imagine that it is 2 times as efficient, then by logic it would take half the time, i.e. Divide by 2 = Multiply by 1/2
