[ 1/1Inequality]
    Assignment:Find the solution set of inequality 0 <180(n-2)-1510 <180 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        0 <180 * ( n - 2 ) - 1510         (1)
        180 * ( n - 2 ) - 1510 <180         (2)

---

    From inequality(1)：
         n ＞ 187/18
    From inequality(2)：
         n < 205/18

---

    From inequalities (1) and (2)
         187/18 < n < 205/18     (3)

---

    The final solution set is :
         187/18 < n < 205/18
