- option c 8
14 mens 1 day work=1/16
1 mens work for 1 day =1/16*14
now 8 men work for 1 day =8/16*14=1/28
now 8 mens work for 12 days=(1/28)*12=3/7
now reaming work after 12 days =4/7
now 8 more joined => 16 mens 1 days work =16/(16*14)=1/14
so for 4/7 work time will be taken by 16 mens = (4/7)14=4*2=8 - 11 years agoHelpfull: Yes(14) No(1)
