please do it very urgent time is very short... I'll give you up thumb definitely

(c) 500kgh1 of a solvent is used to extract oil from 400kgh1ofsoyabeanc in a counter-current leaching process. The beans contain 10wt. \% of oil and 90wt.% of insoluble matter. The underflow retains 0.6kg of solution per kg of insoluble matter. If 96% oil recovery is required, calculate (i) the composition of the product underflow. (5 marks) (ii) the composition of all the streams entering and leaving the primary stage. (8 marks) (iii) the number of stages required using the shortcut method.
