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

### Instruction:
Sylvia had one-fifth of incorrect answers in the exam, while Sergio got 4 mistakes. If there were 50 questions, how many more correct answers does Sergio have than Sylvia?

### Response:
 Ikiwa kulikuwa na maswali 50, na Sergio alipata makosa 4, alijibu maswali 50-4=<<50-4=46>>46 kwa usahihi.
Asilimia moja ya majibu yasiyo sahihi katika mtihani kwa Sylvia ni 1/5 * 50 = <<1/5*50=10>>10 maswali.
Sylvia alijibu maswali 50-10=<<50-10=40>>40 kwa usahihi.
Sergio ana majibu sahihi zaidi ya 46-40=<<46-40=6>>6 kuliko Sylvia.
