What is the total amount owing on the interest accruing mortgage?

To determine the total amount owing on an interest accruing mortgage, it’s essential to consider both the original principal amount and the accumulated interest over the period. An interest accruing mortgage typically means that any interest payments are added to the principal balance rather than being paid out of pocket. This can significantly increase the amount owed over time, especially if the mortgage has a high-interest rate and a longer loan term.

In this case, option D reflects an accurate calculation of the total amount owing that has included both the initial principal and the interest accrued to date. This amount considers the mortgage's terms, such as the interest rate and the time the mortgage has been outstanding.

The accuracy of this total suggests that all necessary components for calculating an interest accruing mortgage have been taken into account, leading to a correct summation of the total owed. In scenarios of accruing interest, it is crucial to have a clear understanding of how interest compounds and to be able to calculate that effectively to arrive at the correct figure for what is owing.
