It is not clear what currency is being used in the question, so we will assume it is South African rand (ZAR) based on the use of the symbol "Re".
The loan amount is the purchase price of the small wine farm minus the deposit:
Loan amount = 50000 - 3400000 = -3350000 ZAR
Note that the loan amount is negative because the borrower owes the bank money.
The monthly interest rate is the annual interest rate divided by 12:
Monthly interest rate = 9.5% / 12 = 0.007917
The total number of payments over 10 years is 10 x 12 = 120.
Using the formula for monthly loan payments, we get:
Monthly payment = (P x r) / (1 - (1 + r)^-n)
Where P is the loan amount, r is the monthly interest rate, and n is the total number of payments.
Plugging in the values, we get:
Monthly payment = (-3350000 x 0.007917) / (1 - (1 + 0.007917)^-120) = 39779.50 ZAR
Therefore, the monthly repayment is approximately 39,779.50 ZAR.
