Person A can finish 2/5 of work and person B can finish 3/5 of work. If A completed some 1/9 of his work and B completed 5/18 of his work. what fraction of work is not yet completed by both?

• [1-(2/45)-(1/6) = 71/90

• the work completed by a = 2/5*1/9=2/45
  completed by b =(3/5)*(5/18)=1/6
  so thw work to be completed =1-(2/45)-(1/6)=71/90

• total work is 1
  A completed 1/9 of 2/5 so ( 1/9)*(2/5)=2/45
  B completed 518 of 3/5 so (5/18)(3/5)=1/6
  remaining work fraction is 1-(2/45)-(1/6)=71/90

• 13/45 of work is not yet completed by Person A.
  16/45 of work is not yet completed by Person B.
  So total of 29/45 of work is not yet completed by both.

• 55/90 as 2/5-1/9=13/45
  and 3/5-5/18=29/90
  29/90+13/45=55/90

• 71/90 of work is still left.
  A+B did (2/5)*(1/9)+(3/5)*(5/18) work
  hence work left is 1-(19/90)

• let w=5 units
  then a's efficiency=2
  b's efficiency=3
  then a's remaining work=(2-2/9)=16/9
  b's remaining work=(3-15/18)=39/18
