10. In disaster relief donations, $\frac{1}{10}$ of the people in a company each donated 200 yuan, $\frac{3}{4}$ of the people each donated 100 yuan, and the rest each donated 50 yuan. The average donation per person in the company is $\qquad$ yuan.
【Solution】Solution: The proportion of people donating 50 yuan is: $1-\frac{1}{10}-\frac{3}{4}=\frac{3}{20}$,
$$
\begin{aligned}
& \left(200 \times \frac{1}{10}+100 \times \frac{3}{4}+50 \times \frac{3}{20}\right) \div 1 \\
= & (20+75+7.5) \div 1 \\
= & 102.5 \text { (yuan) }
\end{aligned}
$$

Answer: The average donation per person in the company is 102.5 yuan.
Therefore, the answer is: 102.5.
