Hi, in fully amortizing bond, principal value is also given out along with the interest payment. so in the end all the amount is paid off. while in partially amortizing bond principal is paid off in the end. also in the book, the question is only for explanatory purposes. there is no need to understand the mathematical calculation in fully amortizing and partially amortizing bonds.
