For a) it should be cash and marketable securities - not all assets. Things such as receivables, fixed assets, long term investments etc are subject to various fluctuations and individual biases.

b) Can be approximated if you have historical balance sheets and income statements. Also in Coco-Colas MD&A section in the yearly reports they will talk about what they bought and when.

C) Coco-cola works on a pure franchise model were all manufacturing, bottling, distribution etc are taken care by 3rd party companies and not Coke themselves. Coke is essentially just a marketing and R&D company. Hence more current assets and less fixed assets.

d) Yup. Fixed assets would have gone down due to the sale. Cash would have increase due to proceeds from the sale.
