    Assignment:Find the solution set of inequality 0 <0.5-(0.1(2-0.02)x)/(4*0.04*(1-x)) <1 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        0 <0.5 - ( 0.1 * ( 2 - 0.02 ) * x ) / ( 4 * 0.04 * ( 1 - x ) )         (1)
        0.5 - ( 0.1 * ( 2 - 0.02 ) * x ) / ( 4 * 0.04 * ( 1 - x ) ) <1         (2)
        From the definition field of divisor
         4 * 0.04 * ( 1 - x ) ≠ 0        (3 )

---

    From inequality(1)：
         x < 0.28777 或  x ＞ 1
    From inequality(2)：
         -0.677966 < x < 1
    From inequality(3)：
         x < 1 或  x ＞ 1

---

    From inequalities (1) and (2)
         -0.677966 < x < 0.28777     (4)
    From inequalities (3) and (4)
         -0.677966 < x < 0.28777     (5)

---

    The final solution set is :
         -0.677966 < x < 0.28777
