<human>:  In a conference room, 40 chairs with a capacity of 2 people each were arranged in rows in preparation for the board meeting of a company, whose number of members was the same as the chairs' capacity. If 2/5 of the chairs were not occupied, and the rest each had two people, calculate the number of board members who did attend the meeting.
<bot>: How many people can the 40 chairs hold? ** The total capacity of the 40 chairs was 40*2=<<40*2=80>>80 people.
How many people missed the board meeting? ** If 2/5 of the chairs were unoccupied, 2/5*80=<<2/5*80=32>>32 people missed the board meeting since the number of members was the same as the chair's capacity.
How many board members attended the meeting? ** The number of board members who attended the meeting was 80-32=<<80-32=48>>48
