D. 12
Solution (By Examveda Team)
Work Rate of Man and Women,
(2/m) + (5/w) = 1/(4*3) ------------------------- (1)
(3/m) + (5/w) = 1/(4*2) -------------------------- (2)
(2) - (1),
1/m = 1/24
m = 24.
It means one man needs 24 days to complete the work so work to be completed in 4 days, we need
24/4 = 6 men.
