Solution :
Work done by Shalini in 5 days = \[\frac{5}{20}\] Suppose Preeti completes the remaining work in x days then, \[\frac{5}{20}+\frac{x+5}{30}=1\] \[\Rightarrow \,\,\,\,\,2x=60-25\Rightarrow x=\frac{35}{2}\,\,days\] \[\therefore \,\,\,\,\,\,\,Total\,\,no.\,\,of\,\,days=\left( \frac{35}{2}+5 \right)days\] = \[\]You need to login to perform this action.
