According to the question
Total fresh fish $=2709\mathit{k}\mathit{g}$
cost price of one $\mathit{k}\mathit{g}$
fresh fish $=\mathit{₹}27$
Total cost price $=27\times 2709=73143$
Total drug fish $=2709\times \frac{1}{3}=903\mathit{k}\mathit{g}$
Selling price of $1\mathit{k}\mathit{g}$
dry fish $=\mathit{₹}97.5$
Total selling price $=903\times 97.5=88042.5$
Total profit $=88042.5-73143=14899.5$
