Answer: According to the meaning of the question, these 32 people happen to live on the second floor to the 33rd floor. For everyone who goes upstairs and downstairs by elevator, the floor he lives in must not be less than that of the person who goes upstairs directly. In fact, people who live on the S floor take the elevator, and those who live on the T floor go upstairs directly. S

Suppose the elevator stops at the X floor, and on the first floor, Y goes upstairs directly without taking the elevator. Then the total score of dissatisfaction is s = 3 [1+2+…+(33-x)]+3 (1+2+…+y)+[1+2+…+.

= 2 x2-xy- 102 x+2 y2+3y+ 1684

= 2 x2-(y+ 102)x+2 y2+3y+ 1684

=2*[x-(y+ 102)/4]？ + 15/8(y-6)？ +3 16

≥3 16 .

When x=27 and y=6, S=3 16.

Therefore, when the elevator stops at the 27th floor, the total score of dissatisfaction is the smallest, and the lowest is 3 16.

(You can even get an equal sign by sorting it out. There is a summation formula, that is, the first term plus the last term multiplied by the number of terms divided by 2. )
