Answer

Explanation:

Step1: Find total number of medium - sized mirrors

First, find the total number of all mirrors: $480 + 402=882$. Then find the number of small and large mirrors: Small total is $102$, large total is $214$. Let the total number of medium - sized mirrors be $x$. So, $102 + x+214 = 882 - 402$ (subtracting the total number of broken mirrors from the grand - total to get non - broken + non - broken medium). $102 + x+214 = 480$, $x=480-(102 + 214)=164$.

Step2: Calculate number of broken medium mirrors

We know the number of non - broken medium mirrors is $96$. Let the number of broken medium mirrors be $y$. Since the total number of medium mirrors is $164$, then $y=164 - 96 = 68$.

Answer:

68
