<PRE><B>Question 396534</B>
a piece of work can be done by 40 men in 48 days,
 after 15 days, 18 men were transferred to another job,
 how many days will the remaining men finish the job?
;
Find how many man-days to complete the job:
40 * 48 = 1920 man-days
:
That leaves 22 men to finish the job in d days
(40*15) + 22d = 1920
:
600 + 22d = 1920
22d = 1920 - 600
22d = 1320
d = {{{1320/22}}}
d = 60 days to complete the job
:
:
Check:
(40*15) + (22*60) = 1920</PRE>
