Answer 1

Dear Student,


$$\begin{gathered} \mathrm{Part}\mathrm{of}\mathrm{the}\mathrm{bill}\mathrm{paid}\mathrm{by}\mathrm{swati}=1-\mathrm{Part}\mathrm{of}\mathrm{the}\mathrm{bill}\mathrm{paid}\mathrm{by}\mathrm{Romila}-\mathrm{Part}\mathrm{of}\mathrm{the}\mathrm{bill}\mathrm{paid}\mathrm{by}\mathrm{Pooja} \\ =1-\frac{1}{3}-\frac{1}{5} \\ =\frac{15-5-3}{15} \\ =\frac{7}{15}\mathrm{ANS}... \end{gathered}$$
