<PRE><B>Question 1031359</B>
 20 men decided to complete the repairing work of a house in 30 days.
man-days to do the job = 20*30 = 600
------------------------------
But after 6 days 8 men fell sick
20 men worked 8 days to complete 160 man-days;
600 - 160 = 440 man-days needed to complete the job
----------------
How long they will take to complete the repairing work?
12 men to complete 440 man days:: 440/12 = 36 2/3 days
----------------------
Cheers,
Stan H.
