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

### Instruction:
 Princeton alifanya sherehe ya kufichua jinsia na aliwaalika wafanyakazi wenzake wote kusherehekea naye. Ikiwa idadi jumla ya wageni walikuwa 60, na 2/3 walikuwa wanaume, wanawake wangapi walihudhuria sherehe?


### Response:
 Idadi ya wanaume katika sherehe ilikuwa 2 wanaume / 3 wageni * 60 wageni = <<2/3*60=40>>40 wanaume.
Ikiwa idadi jumla ya watu katika sherehe ilikuwa 60, basi kulikuwa na 60 wageni - 40 wanaume = <<60-40=20>>20 wanawake.
