Highly likely an error by the publisher. The number should be 0.015, or 1.5/100, to reflect that 3% per annum is equivalent to 1.5% per half year which is required here since the compounding frequency is twice a year.

Typically, I do not always trust given answers 100% of the time, after having experienced faults with many of them. Even Cambridge exams do make very rare errors (but they rectified it before I sat for one paper, in a very very rare occurrence more than ten years ago). You must take the answers given from this book with some degree of doubt.

Something like this would be good.

P.S. You can also doubt my answers to a degree if you are unsure of it.
