i)time taken by A to do the job =9/2days
work it will do in one day=1/(9/2)=2/9
Time taken by B,to do the whole work=9days
work in one day=1/9
work done in one day by A and B together=2/9 +1/9=3/9=1/3
so,time they will take to complete the whole work together=3days
ii)each person will share acccording to their work
Work done by A in these three days,=2/9 ×3=2/3
work done by B in these three days=(1/9)×3=1/3
share of A=2/3 ×3900=2600
share of A=2/3 ×3900=2600share of B=1/3 ×3900=1300
