Given the task definition and input, reply with output. This task involves creating questions from a given passage that involve some kind of complex reasoning (including numerical reasoning).
The generated questions must require looking at more than one part of the passage to answer. Try to use a variety of reasoning types in your questions (some of the sample reasoning types are illustrated in the 'positive examples' field) and also have a variety of answer types (spans, numbers, dates). A span is a continuous phrase taken directly from the passage or question. In such questions, the answer spans are recommended to be five words. Questions with answer type "number", are expected to start with "How many". For instance, "How long did an event last?" can be phrased as "How many years did an event last?". To increase diversity, try to create more questions for which the answer will be multiple spans. Please create questions that require AT LEAST 2 arithmetic operations as illustrated in the 'positive examples' field. You are encouraged to try DIFFERENT COMBINATIONS of operations and not just limit to the combinations shown in those examples. The more challenging questions you create, the better it is.

Passage: French and Savoyard troops numbering over 50,000, under the command of Charles Emmanuel, entered Milanese territory as early as October 24, against minimal resistance, as the Austrian forces in the duchy numbered only about 12,000. By November 3, the city of Milan itself had surrendered, although the Austrian governor, Count Wirich Philipp von Daun, still held the fortress. France's great general, the Duke de Villars, joined Charles Emmanuel in Milan on November 11. While Villars wanted to move immediately against Mantua to secure the Alpine passes against Austrian reinforcements, Charles Emmanuel, mistrustful of his French allies and their dealings with Spain, sought to secure Milan. The army spent the next three months eliminating Austrian opposition from the remaining fortified towns in the duchy. Villars attempted to interest Don Carlos of Parma in joining the expedition against Mantua, but Carlos was focused on the campaign into Naples. Villars began to move against Mantua, but Charles Emmanuel resisted, and the army made little progress. In early May, an Austrian army of 40,000 under Count Claude Florimond de Mercy crossed the Alps and threatened to close in on the French army's rear by a flanking maneuver. Villars responded by retreating from Mantua and attempted without success to interrupt the Austrian army's crossing of the Po River. Villars, frustrated by Charles Emmanuel's delaying tactics, quit the army on May 27. He fell ill on the way back to France and died in Turin on June 17.
By how many troops did the French and Savoyard outnumber the Austrian forces?
