I see that your website has two store views: India and US, right? and you want to sell a product at different prices in this two store views.
In this case, you cannot set up different prices for a product at the level of website because Magento default does not support it. Therefore, you have to do it at the level of store view
I have seen some similar issues related to various prices for store views and it is suggested using an extension called Multiple store view pricing
I also read about it and found out that it can meet your requirement because it allows you to set up different prices for the same product in each store view. By choosing each store view and make adjustments for price, a product will have various prices when displaying in the frontend under corresponding store view.
