Question: Among the sales ID ranges from 1 to 200, what is the percentage of the products with a price ranging from 200 to 300?
SQL: SELECT CAST(SUM(IIF(T2.Price BETWEEN 200 AND 300, 1, 0)) AS REAL) * 100 / COUNT(T2.Price) FROM Sales AS T1 INNER JOIN Products AS T2 ON T1.ProductID = T2.ProductID WHERE T1.SalesID BETWEEN 1 AND 200
