Reason:
1. The total repayment amount is too high: the repayment amount is 84303, which exceeds the original loan by nearly 70%. This means that nearly 70% of the interest and expenses need to be paid in 36 installments, which is a heavy burden.
2. The interest rate is too high: the specific interest rate cannot be known according to the given information, but judging from the gap between the total repayment amount and the loan amount, it is likely that the interest rate is too high.
3. Longer repayment period: The loan is repaid in 36 installments, which increases the repayment pressure of the borrower and may lead to more interest expenses.
4. Lack of relevant background information: There is very little conditional information mentioned in the answer, and it is impossible to know important factors such as the reputation of the loan platform and the credit status of the borrower. Without other necessary information, especially the details related to interest rates and expenses, it is difficult to make an accurate judgment.
Summary:
According to the information given, it seems unreasonable to repay 84303 with 50000 installments. Borrowers should carefully consider the high repayment amount and possible high interest rate, and also pay attention to the loan term and the reliability of the loan platform. Before making a decision, it is recommended to consult a professional for more relevant information.
