Answer:
8days
Step-by-step explanation:
4 men need 16 days
4M=16
one man needs 4×16days
M =64 days
6 women need 16days,
6W = 16
one woman needs 6×16 days
W = 96
LCM of 64 and 96 is 192
efficiency of man =192/64 =3
efficiency of woman =192/96=2
For 2men and 9 women,
total efficiency = (2×3) + (9×2)
=6+18
=24
required days to complete that work =192/24
=8 days
