【Solution】Solution: Let the number of pages in the *Book of Songs* be $a$, then:
$$
a \square 24 \square 17 \square 27 \square 19=a \square 15
$$

It is easy to know:
$$
a+24-17+27-19=a+15
$$

Therefore:
$$
\begin{array}{l}
\text { *Book* }=a+24, \\
\text { *Rites* }=a+24-17=a+7, \\
\text { *Changes* }=a+7+27=a+34 \\
\end{array}
$$
