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

### Instruction:
Christi saw twice as many black bears as white bears and 40 more brown bears than black bears in a national park. If the number of black bears in the park is 60, calculate the population of bears in the park.

### Response:
 Ikiwa kuna dubu weusi 60 katika hifadhi na dubu wa kahawia 40 zaidi ya dubu weusi, kuna dubu wa kahawia 60+40 = <<60+40=100>>100.
Idadi ya dubu weusi na dubu wa kahawia katika hifadhi ni 100+60 = <<100+60=160>>160
Mara mbili ya idadi ya dubu weusi kama dubu weupe inamaanisha dubu weupe 60/2 = <<60/2=30>>30
Idadi ya dubu katika hifadhi ya taifa ni 30+160 = <<30+160=190>>190
