The question gives the YTM as 5%. Doesn't that mean that the BEY is \Large $$\sqrt{1.05}-1$$\cdot 2 or 4.939%? When using the calculator to find the price of the bond, isn't the semi-annual interest rate \Large \sqrt{1.05}-1 or 2.4695%, and not 2.5%?

I thouught 2.5% would be the semi-annual rate if the bond-equivalent rate was 5.0%?

The first thought I saw this questions was 2.5% semi-annual rate. But what you said seem to make sense.

I will think like this way:

if it is given associated with a price, then it is simple interest
If they require you to calcaulate a yield to maturity, then it is compunded annually.

YTM is a type of yield. BEY is a unit of measurement. A YTM may be quoted as either an Effective Annual Yield or as a Bond Equivalent Yield. It looks like, in this context, the YTM was assumed to be quoted as a BEY -- this is how it's quoted in the WSJ.

Not clear about whether this type of question is still in the readings. New editions of both BKM and Hull have come out since '04.
