11. (6 points) In an exam, the average score of $A, B, C, D, E$ is 90 points. If the average score of $A, B, C$ is 86 points, and the average score of $B, D, E$ is 95 points, then the score of $B$ is $\qquad$ points.
【Analysis】According to "average $\times$ quantity $=$ total", calculate the sum of the three numbers $A, B, C$ and the sum of the three numbers $B, D, E$, as well as the sum of these five numbers, and then use "sum of $A, B, C$ + sum of $B, D, E$ - sum of five numbers" to solve.

【Solution】Solution: $(86 \times 3+95 \times 3)-(90 \times 5)$,
$$
\begin{array}{l}
=543-450, \\
=93 \text { (points); }
\end{array}
$$

Therefore, the answer is: 93.
