4 day in work =2 men + 17 women
1 day in work = 4 ( 2 men + 17 women )
= 8 men +68 women
3 day in a work= 4 men +4 women
1 day in a Work =3 (4 men+ 4 women )
. 12 men + 12 women
8 men + 68 women= 12 man+12 women
68 women _12 men= 12 man_8 man
56 women =4 man
14 women =1 man
2man+17 women =(2×14+17)=
45 women
1 men +1 women = 1 ×14 +1 =15 women
45 women do one work =4 days
1 .....................................=4 ×45=180 days
15...................................=180/15=12 days
one man and one women =12 days
