Number of days for one man = 15 x 12 = 180 days
Number of days for one woman = 20 x 12 = 240 days
If the work is done individually,
∴ number of days for 5 men = 180/5 = 36 days
number of days for 5 women = 240/5 = 48 days
If both did the same work = 36/2 + 48/2 = 18 + 24 = 42 days
Number of days for one woman = 20 x 12 = 240 days
