a) 8
b) 6
c) 12
d) 16
e) None of these

Click here to View Answer
Answer c) 12
Explanation:
8 men complete in 6 days = (8 * 6) / (12 * 8) = 1/2 of the work
8 women complete the work in (6 + 1) = 7 days
(8 * 7) / (16 * 12) = 7/24 of the work
Remaining work = 1 – (1/2 + 7/24) = 5/24
Now, in one day 5/24 part of the work is done by (12 * 8 * 5) / 24 = 20 men
Additional number of men = 20 – 8 = 12.

Then, Area of the floor = 16 * 12 = 192 m^2.
