Soybean of \( 20 \) per cent oil is solvent extracted to leave meal at \( 0.6 \) per cent oil. From \( 1000 \) kg of seed the meal weighs about
Answer: B
Non-oil solids are \( 800 \) kg and they form \( 99.4 \) per cent of the meal, so the meal is \( 800/0.994 = 804.8 \) kg. Ignoring the residual oil and quoting 800 kg is the usual approximation and is very nearly right.
