10. The school library has purchased extracurricular reading materials for four grades, among which 110 are not for the first grade, 108 are not for the second grade, 104 are not for the third grade, and 119 are not for the fourth grade. In this case, the school has purchased extracurricular reading materials for the first grade, second grade, third grade, and fourth grade as follows: $\qquad$ books, $\qquad$ books, $\qquad$ books, $\qquad$ books.
【Analysis】 $37,39,43,28$
$$
\begin{array}{l}
\text { Two+Three+Four }=110 ; \\
\text { One+Three+Four }=108 ; \\
\text { One+Two+Four }=104 ; \\
\text { One+Two+Three }=119 ;
\end{array}
$$

Get One + Two + Three + Four $=(110+108+104+119) \div 3=147$;
Subtract the above four equations in sequence to get: One $=37$, Two $=39$, Three $=43$, Four $=28$.
