Right answer is (c) 55.6 kg of component A to 44.4kg of component B

To explain: Let the proportions be X of component A to Y of component B

Then by a mass balance on the fat,

(X × 0.23)+ (Y × 0.05) = (X+Y) × 0.15

A (0.23-0.15) = B (0.15-0.05)

A (0.08) =B (0.10)

A/B= 5/9

Therefore, 100kg of product will have 55.6 kg of component A to 44.4kg of component B.
