[Q. ] PP1 PS27
D)27. 3330-!-item-!-187;#058&003295
38, 69, 22, 73, 31, 47, 13, 82
Which of the following numbers is greater than
three-fourths of the numbers but less than one-fourth of
the numbers in the list above?
(A) 56
(B) 68
(C) 69
(D) 71
(E) 73
從解答中得知這題是在問哪個數「大於數列的第3/4個數，小於數列的第1/4個數」
數列從新排列後是 13 22 31 38 47 69 73 82
8*3/4=6 第六個數是69
8*1/4=2 第二個數是73(?)
所以答案是(D)71
疑問點：為何one-fourth of the numbers 數列的第1/4個數是 73而不是 22?
