a take 12 hr to publish a book,b take 10 hr.find the time by them to make two publications working independently.

• A => 12hr
  B => 10hr,
  wen taking LCM,its 60 which gives A's work in hour is 5.B's work in hour is 6.
  
  Now the point is they have to complete 2 publications, therefore total work = 60*2= 120
  
  A and B's total work per hour = 5+6 =>11
  
  therefore time taken for 2 publications = 120/11 => 11(9/11)...

• here they r working independently and the target is to complete two publications
  'b' can do a publication in 10hrs and 'a' took 2 more hrs to complete his publication. Total two publications are done
  therefore answer is 10+2=12
