问题 s, t, and u are integers, and 10≤s＜t＜u≤20
Quantity A: s+t/u
Quantity B: 11
选项 A、Quantity A is greater.
B、Quantity B is greater.
C、The two quantities are equal.
D、The relationship cannot be determined from the information given.
答案 D
解析 s+t/u：s越大；t越大，u越小，值越大。当s=10，t=11，u=20时，取得最小值；当s=18，t=19，u=20，取得最大值。故答案为D。
