For total cholesterol 275, ldl-177, hdl-40, triglycerides-190, what should be the ideal dose of statin ?

I say ZERO: Most docs disagree, but the ideal dose is zero. Statins have never been shown to extend life by even a day & can cause serious side effects. See http://www.Sott.Net/article/242516-heart-surgeon-speaks-out-on-what-really-causes-heart-disease & http://www.Cbn.Com/cbnnews/healthscience/2012/october/cholesterol-myth-what-really-causes-heart-disease/ & http://www.Spacedoc.Com/cholesterol_articles.

Depends : The use of a statin or other lipid altering agent should be used in the context of that particular patients cardiovascular risk. In patients with genetic/inherited disorders of lipid metabolism, such as familial hypercholesterolemia (fh) those treated with statins reduce risk back to normal patients. For others, treatment depends on risk benefit profile. Preventing a stroke is a good thing.
