Calculate the annual interest rate that was used on the balance brought forward to obtain the credit interest. You may use the following formula: Annual interest rate = (Credit Interest x 365 / Balance Brought Foward) x 100

To solve questions 1.1.3, 1.1.4, and 1.1.6, I need to see the bank statement or table that contains the financial data (like "Credit Interest", "Balance Brought Forward", and the values A, B, C, D). This information is not visible in the image you sent. Please provide the full image including the table/statement.

However, I can answer question 1.1.5 conceptually.

1.1.5
