Question

一幅条形图显示了一家快餐连锁店在每个季节卖出的汉堡数量。但是，表示冬季销量的条形被一块污迹遮住了。如果这家连锁店全年汉堡销量中正好有 $25\%$ 是秋季卖出的，那么冬季卖出多少百万个汉堡？

A bar graph shows the number of hamburgers sold by a fast food chain each season. However, the bar indicating the number sold during the winter is covered by a smudge. If exactly $25\%$ of the chain’s hamburgers are sold in the fall, how many million hamburgers are sold in the winter?

$2.5$

$3$

$3.5$

$4$

$4.5$

答案：A

知识点：百分数

难度评级：960

小提示：

秋季销量 $4$ 百万个是全年总量的 $25\%$ ，所以先求全年总量

The fall sales of $4$ million are $25\%$ of the yearly total, so find the yearly total first

大提示：

从全年总量中减去春、夏、秋三季销量

Subtract the spring, summer, and fall sales from the yearly total

解答：

如果秋季 $4$ 百万个是全年总量的 $25\%$ ，那么全年总量是 $16$ 百万个。

冬季销量是 $16 - (4.5 + 5 + 4) = 2.5$ 百万个。

所以正确答案是 A。

If the fall sales of $4$ million are $25\%$ of the yearly total, then the yearly total is $16$ million.

The winter sales are $16 - (4.5 + 5 + 4) = 2.5$ million.

Thus, the correct answer is A .
