    Assignment:Find the solution set of inequality 0.0005x^2-0.1903x+20.97-(0.001x^2-0.5487x+81.074) <0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        0.0005 * x ^ 2 - 0.1903 * x + 20.97 - ( 0.001 * x ^ 2 - 0.5487 * x + 81.074 ) <0         (1)

---

    From inequality(1)：
         x < 267.611454

---

    The final solution set is :
         x < 267.611454
