In the double-decker bus I took, there were 25 passengers including me on the first floor. The conductor told me that the number of passengers on the second floor was 40% of that on the first floor. So how many people are there in total in this car?
我乘坐的双层巴士中，1层连我在内一共有25名乘客，售票员告诉我2层的乘客人数是1层的40%．那么这辆车上总共有多少人．
<gadget id="calculator">40 / 100</gadget>
<output>2/5 = around 0.4</output>

<gadget id="calculator">25 * (2/5)</gadget>
<output>10</output>

<gadget id="calculator">25 + 10 + 2</gadget>
<output>37</output>

<result>37</result>
