The sum of the integers in list S is the same as the sum of the integers in list T. Does S contain more integers than T ?

(1) The average (arithmetic mean) of the integers in S is less than the average of the integers in T.

(2) The median of the integers in S is greater than the median of the integers in T.

答案 A

請問一下各位

sum=avg*個數

在avg和sum是正數的情況下，avg越小，個數就越多，這部分沒問題；


但若遇到sum<0情況時，情況會完全相反，

sum<0 必定avg<0

avg越小 個數就越少



這樣有兩種解釋，是否還符合資料充分性嗎??
