• 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

• Applying same mt principle
  
  mt=mt --- >
  
  14*16=(8*12)+(x*12)
  
  On Simp. --->x=8
