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 60-item exam, Liza got 90% of the items correctly. Her best friend, Rose, got 2 more correct answers than her. How many incorrect answers did Rose have?

### Response:
 Liza alipata maswali 60 x 90/100 = <<60*90/100=54>>54 kwa usahihi.
Hivyo, Rose alipata maswali 54 + 2 = <<54+2=56>>56 kwa usahihi.
Hivyo, Rose alikuwa na majibu yasiyofaa 60 - 56 = <<60-56=4>>4.
