    Assignment:Find the solution set of inequality (20-3/8x)x+(100-x)(1+2.5x%)*10 >1400 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 20 - 3 / 8 * x ) * x + ( 100 - x ) * ( 1 + 2.5 * x % ) * 10 >1400         (1)

---

    From inequality(1)：
         16 < x < 40

---

    The final solution set is :
         16 < x < 40
