Engineering material casting help

I need answers for questions 1, 2, and 3 pertaining to the print provided.

bliuzodt to mopolb 9. If machine parts are degreased by means of kerosene as shown in the diagram, how much kerosene make-up is needed per day? How much kerosene has to enter the degreasing vat per day? There are about 3 lb of grease per 100 lb of machine parts, and 60 tons of machine parts are processed each day. Five thousand pounds of kerosene (the 10% solution) are carried away by the machine parts each day but drip off and are caught and put back in the degreasing vat. Two hundred pounds of the 10% solution are lost each day from the vat by evaporation, spillage, or by being carried away.
