Phytase, an enzyme produced by Aspergillus niger can be adsorbed on microcrystalline cellulose powder (MCCP). The adsorption follows a Langmuir isotherm and the maximum concentration of the protein that can be obtained on the adsorbent is 70 mg cm-1. At a concentration of 50 mg L-1 of protein in the solution, the concentration of protein on the adsorbent reaches 35 mg cm-1. It is desired to recover 90% of the protein from 1.5 liter of the cell free culture filtrate containing 220 mg L-1 protein by addition of MCCP to the solution. The concentration of the protein adsorbed on the solid at equilibrium will be:
Skim milk is prepared by the removal of some of the fat from whole milk. This skim milk is found to contain 90.5% water, 3.5% protein, 5.1% carbohydrate, 0.1% fat and 0.8% ash. If the original milk contained 4.5% fat, Calculate its composition assuming that fat only was removed to make the skim milk and that there are no losses in processing.
A milk vendor has 2 cans of milk. The first contains 25% water and the rest milk. The second contains 50% water. How much milk should he mix from each of the containers so as to get 12 litres of milk such that the ratio of water to milk is 3 : 5?
A milk vendor has 21 litres of cow milk, 42 litres of toned milk and 63 litres of double toned milk. If he wants to pack them in cans, so that each can contains same litres of milk and does not want to mix any two kinds of milk in a can, then the least number of cans required is = ?
Directions : In each of the following questions a statement is given, followed by two conclusions. Give answer :

Statements : About 50 per cent of the animal by-products - hair, skin, horns etc. is edible protein. American chemists have developed a method of isolating 45 per cent of this protein. They used an enzyme developed in Japan to break down soya protein.

Conclusions :
I. Americans have not been able to develop enzymes.
II. Animal by-products protein has the same composition as soya protein.
Out of 10 employees in an office 5 drink 2 cups of coffee per day, 3 drinks 3 cups of hot chocolate per day and 2 drink 5 cups of tea per day. If it is known that on an average to make a cup of coffee 100 ml of milk is used, to make a cup of hot chocolate 180 ml of milk is used and to make a cup of tea 60 ml milk is used, find the monthly expenditure on milk of the company, if milk is 46 rupees per liter.
There are 40 animals in a zoo and per animal 20 packets of milk is required. One pack of milk contains 200 ml of milk, and milk costs 46 rupees per litre. If the employees of the zoo fulfil only 80% of the animal’s intake of milk what will be the expenditure of the zoo?
From the 50 liters of milk, 5 liters of milk is taken out and after it 5 liters of water is added to the rest amount of milk. Again 5 liters of milk and water is drawn out and it was replaced by 5 liters of water. If this process is continued similarly for the third time, the amount of milk left after the third replacement:
A dishonest milk man mixed 1 liter of water for every 3 liters of milk and thus made up 36 liters of milk. If he now adds 15 liters of milk to mixture, find the ratio of milk and water in the new mixture:
