• (12*10)/(12+10)=120/22 answer
• 12 years agoHelpfull: Yes(1) No(24)

• since A does the work in 12 hrs
  So , in an hr 1/12 work is done by A.
  and similarly in an hr, 1/10 work is done by B.
  Therefore together in an hr,they do(1/12+1/10)=4/15 of the work.
  
  Now,since they both can do 4/15 of the work in 1 hr
  therfore " " " " " 1 work in 15/4 hr i.e 3hr and 45 minutes

• Ans: 12 hours
  
  I interpret this question as "A starts to make a publication" and at the same time 'B starts to make another publication'
  
  After 12 hours, A completes his publication. By this time, B must have already completed his publication(as B needs only 10 hours). So answer is 12 hours

• A's 1 day job is == 1/12
  B's 1 day job is ==1/10
  (a+b)'s job is ((1/10)+(1/12)) == 11/60
  both can finish the work in 60/11

• According to the question,
  A and B have to complete 2 publications(1 publication by A and 1 by B)
  So, A will take 12 hrs and B will take 10 and hence 2 publications will be done within 12 hrs
  So, 12 hrs Ans
