The cost of 7kg of potatoes = ₹42.

$\sf The \; cost \; of \; 1kg\; of\: potatoes = \dfrac{Cost \: of \:7kg \:of \:potatoes}{7}$

$\implies \sf The \; cost \; of \; 1kg\; of\: potatoes = \dfrac{42}{7}$

$\implies$ The cost of 1kg of potatoes = ₹6.

$\sf The \; weight \; of \: potatoes \; in \; kg \; that \; can \; be \; purchased \; for \;Rs 96 = \dfrac{96}{Cost \; of \; 1kg\; of\: Potatoes}$

$\implies \sf The \; weight \; of \: potatoes \; in \; kg \; that \; can \; be \; purchased \; for \;Rs 96 = \dfrac{96}{6}$

$\implies \sf The \; weight \; of \: potatoes \; in \; kg \; that \; can \; be \; purchased \; for \;Rs 96 = 16kg.$
