Could the same question be asked of you to provide some basis for your claim that the Hindu belief in one God is not "the most common" in the East? And, as was pointed out, there's a difference between what people in villages might believe compared to a consensus of pandits.
Indeed it could. I get my information from Hindus and how they practice mostly. In temples you see many Gods, and I've been to over a hundred of those. But to do some sort of survey on how individuals perceive it would be quite impossible. The monotheism in Hinduism isn't exclusive monotheism. But i will confess I don't know for sure. Just open to possibilities, and I often question where information is gotten from in anything involving my faith. If anything, we're mostly henothists, which is a sort of qualified monotheism.
