    Assignment:Find the solution set of inequality A/250*lnA-(1-A)/250*ln(1-A)+0.01*A*(1-A) <0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         A / 250 * ln A - ( 1 - A ) / 250 * ln ( 1 - A ) + 0.01 * A * ( 1 - A ) <0         (1)
        From the definition field of ln
        x > 0        (2 )
        From the definition field of ln
         1 - x > 0        (3 )

---

    From inequality(1)：
         0 < A < 0.033385
    From inequality(2)：
         A ＞ 0
    From inequality(3)：
         A < 1

---

    From inequalities (1) and (2)
         0 < A < 0.033385     (4)
    From inequalities (3) and (4)
         0 < A < 0.033385     (5)

---

    The final solution set is :
         0 < A < 0.033385
