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

### Instruction:
 Kati ya wanafunzi 150, 60% ni wasichana na wengine ni wavulana. Ni wavulana wangapi ambao hawakuhusika na klabu za chuo kikuu?


### Response:
 Kati ya wanafunzi 150, 100% - 60% = 40% ni wavulana.
Kati ya wavulana 150 x 40/100 = <<150*40/100=60>>60, 60 x 1/3 = 20 walijiunga na klabu za chuo kikuu.
Hivyo, wavulana 60 - 20 = <<60-20=40>>40 hawakuhusika na klabu za chuo kikuu.
