    Assignment:Find the solution set of inequality [(22500-400Q)/2]^2-40000(900+Q^2) >0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( ( 22500 - 400 * Q ) / 2 ) ^ 2 - 40000 * ( 900 + Q ^ 2 ) >0         (1)

---

    From inequality(1)：
         Q < 161/8

---

    The final solution set is :
         Q < 161/8
