Wharton is exceptionally tough to get into, particularly with a GMAT below 700. Since you are looking to manage a manufacturing company, you should think about targeting schools with strong operations/production programs. Marketing will be important, but you can't sell a product that isn't well and efficiently made. USNews gives top ten lists by specialty. Look first at those schools that have GMAT scores below 700 - Carnegie Mellon, Purdue, and Ohio State in production. Indiana and Ohio State both have excellent marketing programs and somewhat higher acceptance rates.
Any well-respected school will have a strong strategy program - every function is strategy-based in the end. I am not as familiar with European schools by function and the FT doesn't break out rankings that way.
As you know, the pool of applicants from India is huge and acceptance is very competitive. Your strength is in your operations background as opposed to the strictly technical applicants. You will want to stress your operations efforts. If you work directly with hourly workers that will give you very different insights than those of the people who work only with other technically-trained individuals. Those are differences that you can use to make your application more compelling.
Good luck,
Tani Wolff
