9 men can do in 20d
1 man can do in 1 d =1/180
12 women can do in 18d
1 woman can do in 1 day =1/216
6 men and 9 women can do in 1 day =6*1/180+9*1/216
=1/30+1/24 = 9/120=3/40
In 8 days =3*8/40=3/5
Remaining=2/5
8 men +6 women =8/180+6/216=2/45+1/36
=(8+5)/180=13/180
No of days to be taken for 2/5 work
(2/5)/(13/180)=2*180/5*13
=72/13
So my option is 5👈
Is this solution helpfull? Yes (1) | No
