Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
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.

### Response:
 Uwezo jumla wa viti 40 ulikuwa 40*2=<<40*2=80>>80 watu.
Ikiwa 2/5 ya viti havikuwa vimejazwa, watu 2/5*80=32 hawakuhudhuria mkutano wa bodi kwa kuwa idadi ya wanachama ilikuwa sawa na uwezo wa viti.
Idadi ya wanachama wa bodi waliohudhuria mkutano ilikuwa 80-32=<<80-32=48>>48.
