8. (10 points) One noon, Sun Wukong ate 10 peaches, and Zhu Bajie ate 25 buns. Sun Wukong said Zhu Bajie ate too much, but Zhu Bajie said his buns were much smaller than the peaches, and it was still Sun Wukong who ate more. The clever Sha僧 used a balance to get the two situations shown in the figure (circles are peaches, triangles are buns, and rectangles represent weights of the marked values), so 1 peach and 1 bun together weigh $\qquad$ grams.

Note: "Sha僧" is a literal translation of "沙僧," which is a character's name. In English, it would typically be written as "Sha Seng." If you prefer, I can adjust it to "Sha Seng" for consistency with the English version of the story. Let me know if you need any further adjustments!

【Solution】Solution: From the figure, we know:
$$
\begin{array}{l}
O=2 \triangle+40 \text { grams } 1 \text {. } \\
+80 \text { grams }=\triangle+200 \text { grams (2) }
\end{array}
$$
$$
\text { From (2), we know: } O=\triangle+120 \text { grams (3) }
$$

Substituting (3) into (1) gives:
$$
\begin{array}{l}
\triangle+120 \text { grams }=2 \triangle+40 \text { grams } \\
\triangle+120 \text { grams }-40 \text { grams }=2 \triangle+40 \text { grams }-40 \text { grams } \\
\triangle+80 \text { grams }=2 \triangle \\
\triangle+80 \text { grams }-\triangle=2 \triangle-\triangle \\
\triangle=80 \text { grams }
\end{array}
$$

Substituting $\triangle=80$ grams into (3) gives:
$O=200$ grams
$$
200+80=280 \text { (grams) }
$$

Answer: 1 peach and 1 bun together weigh 280 grams.
The answer is: 280.

Note: "Sha僧" is translated as "Sha Seng" in the context of the story, but it was left as "Sha僧" in the original text. If you prefer, it can be corrected to "Sha Seng."
