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

### Instruction:
There are 80 passengers on the airplane where the number of men and women is equal. The rest of the passengers are children. How many children are on the airplane if there are 30 men?

### Response:
 Kwa kuwa idadi ya wanaume na wanawake ni sawa, basi jumla ya wanaume na wanawake ni 30 + 30 = <<30+30=60>>60.
Hivyo, watoto 80 - 60 = <<80-60=20>>20 wako kwenye ndege.
