[ 1/1Inequality]
    Assignment:Find the solution set of inequality （16/（0.5A-0.03））+(35/(0.5A-0.05)) ≤(20/0.02) .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 16 / ( 0.5 * A - 0.03 ) ) + ( 35 / ( 0.5 * A - 0.05 ) ) ≤ ( 20 / 0.02 )         (1)
        From the definition field of divisor
         0.5 * x - 0.03 ≠ 0        (2 )
        From the definition field of divisor
         0.5 * x - 0.05 ≠ 0        (3 )

---

    From inequality(1)：
         A ≤ 0.1 或  A ≥ 0.192327
    From inequality(2)：
         A < 3/50 或  A ＞ 3/50
    From inequality(3)：
         A < 1/10 或  A ＞ 1/10

---

    From inequalities (1) and (2)
         A < 3/50 或  3/50 < A ≤ 0.1 或  A ≥ 0.192327    (4)
    From inequalities (3) and (4)
         A < 3/50 或  3/50 < A < 1/10 或  A ≥ 0.192327    (5)

---

    The final solution set is :
         A < 3/50 或  3/50 < A < 1/10 或  A ≥ 0.192327
