Answer 1

Dear student
$$\begin{gathered} \mathrm{Cost}\mathrm{price}\mathrm{of}6\mathrm{dozens}\mathrm{of}\mathrm{apples}=6\times 80=\mathrm{Rs}480 \\ \mathrm{Loss}=5\% \\ \mathrm{So}\mathrm{loss}=\frac{5}{100}\times 480=24 \\ \mathrm{So},\mathrm{selling}\mathrm{price}\mathrm{of}6\mathrm{dozens}\mathrm{of}\mathrm{apples}=\mathrm{Cost}\mathrm{price}-\mathrm{loss} \\ =480-24 \\ =456 \\ \mathrm{So}\mathrm{selling}\mathrm{price}\mathrm{of}1\mathrm{dozen}=\frac{456}{6}=\mathrm{Rs}76 \\ \mathrm{So}\mathrm{the}\mathrm{selling}\mathrm{price}1\mathrm{apple}=\frac{76}{12}=\mathrm{Rs}6.3 \end{gathered}$$
