- As in the above question it is said that the two persons are working independently....
it means both persons are not supporting each other....
so A will complete one publication in 12 hrs....
And B will complete in 10 hrs....
total time will be 12 hrs....
within this period A will also complete one publication and B will also complete another publication within this 12 hrs.....
options are wrong.. - 10 years agoHelpfull: Yes(10) No(2)

B one day work=1/10
so that 1/12+1/10=60/11
therfore it time taken by the 2 publications independently=5.45 - 10 years agoHelpfull: Yes(6) No(5)
