R2500 is borrowed for 9 months at an interest rate of 10% per annum simple. What amount is due at the end of 9 months?
R4750
R21250
R2687.50
R187.50
R2325.58
The formula for simple interest is I = P x r x t, where I is the interest, P is the principal amount borrowed, r is the interest rate per period, and t is the number of periods.
In this case, P = R2500, r = 0.10, and t = 9/12 (convert 9 months to years). Plugging these values into the formula:
I = 2500 x 0.10 x 9/12
I = 2500 x 0.10 x 0.75
I = 250
Therefore, the interest due at the end of 9 months is R250.
The total amount due at the end of 9 months is the principal plus the interest,
Total amount = Principal + Interest
Total amount = R2500 + R250
Total amount = R2750
Therefore, the amount due at the end of 9 months is R2750.
