Explanation:

Solution :
18 men work/36 women work = 9/10
To get 1 men work/1 women work divide 9 by 18 and 10 by 36
1 men work/1 women work = (9/18)/(10/36)
= 18 : 10
Now multiply by 12*18 and 18*10 (no. of men and women as given in ques 12 men and 18 women)
12*18 : 18*10 = 6 : 5 (This is the ratio of work)
Hence ratio of days = 5 : 6
difference => 1 = 2
hence 5 = 10 days
