Answer 1

Step-by-step explanation:

$\bf \: Let \: the \: cost \: of \: 8 \: quintals \: of \: soyabean \: be \: Rs \: x. \\ \\ \bf The \: quantity \: of \: soyabeans \: and \: their \: cost \: are \: in \: direct \: proportion. \\ \\ \bf ∴ \frac{12}{36000 }= \frac{8}{x } \\ \\ \bf∴ 12x = 8 × 36000 ….(Multiplying \: both \: sides \: by 36000x) \\ \\ \bf ∴ x = \frac{(8 \: x \: 36000)}{12} = 24000 \\ \\ \bf ∴ The \: cost \: of \: 8 \: quintals \: of \: soyabean \: is \: Rs \: 24000.$
