$\red{Your \: question - }$

$If \: 7 \: kg \: onions \: cost \: 140 \: \\ rupees , \: how \: much \: must \: we \: pay \: \\ for \: 12 kg \: onions.$

$\green{Solution-}$

$Let \: the \: cost \: of \: 12kg \: of \: onions \\ \: be \: x$

$\therefore \: \frac{7}{140} = \frac{12}{x} \\ 7x = 140 \times 12 \\ x = \frac{140 \times 12}{7} \\ x = 20 \times 12 \\ x = 240 \\ \therefore \: The \: cost \: of \: 12kg \: onions \\ \: is \: ₹240$
