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

### 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:
One-fifth of incorrect answers in the exam is 1/5 * 50 = <<1/5*50=10>>10.
Sylvia got 50 - 10 = <<50-10=40>>40 correct answers.
Sergio got 50 - 4 = <<50-4=46>>46 correct answers.
Sergio got 46 - 40 = <<46-40=6>>6 more correct answers than Sylvia.
