Answer 1

Dear student,

$$\begin{gathered} Costof1kgofpotatoes=Rs10 \\ Costof\frac{5}{2}kgofpotatoes=Rs10\times \frac{5}{2}=Rs5\times 5=Rs25 \\ Now, \\ Costof1kgoftomatoes=Rs\frac{192}{11} \\ Asitisnotgiveninthequestionhowmuchkgoftomatoesarebought \\ So,\mathrm{co}nsideringletXkgoftomatoesarebought. \\ then, \\ CostofXkgoftomatoes=Rs\frac{192}{11}\times X=Rs\frac{192X}{11} \\ So,themoneyshegavetotheshopkeeper=Rs\left(25+\frac{192X}{11}\right) \end{gathered}$$
