Answer:
From the given variables, an outsider might be able to understand roughly 35% of the organization's culture.
Explanation:
Culture is ultimately a state of mind, a mode of perception and a collective conscious.
Symbols, Ceremonies, dress and other observable aspects of culture reflects a certain degree of the internal culture, yet to understand it full, it is vital to observe the human behavior and the inter relationships within the organization.
Moreover, the power distance between ranks, distribution of authority and responsibilities, reward systems, means of communication and organizational goals also influences the culture within a company. These aspects are difficult for an outsider to see as they do not stay inside and get exposed to the internal environment of the organization.
