I used a trick but am not sure if it is totally correct.

I use 1P95=e^(-mu) get mu=.51

then I use 2.5P95 = e^(-2.5mu) to get the answer.

Is there anything wrong with this short cut?

Constant force of mortality for interpolating between integral ages is no longer on the syllabus.

In this problem, they arranged the mortality so that q95=q96=q97. If you realized this, then you know that mu95=mu96=mu97, and your trick works. If this weren't true, your trick wouldn't work, since mu at each age would be different.

I am wondering is there any place list the topics off the 2005 CAS syllablus? Or any suggestions?
I really don't know "Constant force of mortality for interpolating between integral ages is no longer on the syllabus. " (I couldn't see it from current syllbus) I am so sad that I am wasting my time on these topics. I might be still doing so. :(

My suggestion would be to use a study manual instead of just the old exams. It's good that you're trying to do old exam problems but many of the study manuals will have old exam questions in them. The people who wrote these manuals would (at least in theory) understand what is and what is not on the syllabus anymore.

It's probably too late for this advice now, but I would recommend this for future tests.
