A can do a work in 36 days where as A and B together can do the same work in 24 days. if B has to do the work alone, how many days will take to complete it ?
[A] 64
[C] 48
[B] 20
[D] 72

• A's one day work is 1/36
  A and B's one day work is 1/24
  generally B's one day work is->A+B one day work-A's one day work
  1/24-1/36=3-2/72
  =1/72
  B's one day work is 1/72
  so B complete the work in72 days

• SAME WORK THEREFOR
  A*36=(A+B)*24
  36A=24A+24B
  A=2B
  so logicaly.....if A can do it in 36 days so B can do the same work in 72 days
