Answer: (1) 4 days
Explanation:-
Given-
3 men or 5 women can do a work = 12 day
5 women = 3 men
Therefore, 1 women = 3/5 men
M 1 = 3 men . D 1 = 12, M 2 = 6 men  &  D 2 = ?

Formula-
M 1 D 1 = M 2 D 2
Where, M = number of men  & D number of days.

Then, 3 x 12 = D 2 x (6 + 5 x 3 / 5)
36 = D 2  x 9
D 2 = 36 /9
D 2 = 4 days

Hence, the answer is (1) 4 days.
