Bran of \( 500 \) kg at \( 18 \) per cent oil is extracted to \( 1.0 \) per cent residual oil in the meal. The oil recovered is about

  • A.90.0 kg
  • B.5.0 kg
  • C.81.0 kg
  • D.85.9 kg

Answer: D

Solids are \( 410 \) kg and the meal weighs \( 410/0.99 = 414.1 \) kg holding \( 4.1 \) kg of oil, so \( 90 - 4.1 = 85.9 \) kg is recovered. Rice bran's oil content makes it a significant source despite the stabilisation it demands.
