C) 6
D) 5
Correct Answer: B
Solution :
Let the work be completed in \[x\]days. According to the question, A worked for \[(x-3)\] days, while \[B\] worked for\[x\] days. \[\therefore \] \[\frac{x-3}{9}+\frac{x}{18}=1\] \[\Rightarrow \] \[\frac{2x-6+x}{18}=1\] \[\Rightarrow \] \[3x-6=18\] \[\Rightarrow \] \[3x=18+6=24\] \[\because \] \[x=\frac{24}{3}=8\]daysYou need to login to perform this action.
