IF 6 MEN CAN FINISH THE JOB IN 14 DAYS THEN THEY EXPEND 6*14=84 MANDAYS.
84/21=4 MEN ARE REQUIRED TO SPEND 21 WORK DAYS TO COMPLETE AN 84 MANDAY PROJECT.
-----------------------------------------------------------------------
6/14=x/21 now cross multiply
14x=6*21
14x=126
x=126/14
x=9 days IF the relationship between painters and days holds.
