Answer

Explanation:

Step1: Find total medium - sized mirrors

We know that the total number of mirrors is 480 and the number of non - medium mirrors (small + large) can be found from the table. The number of small mirrors is 102 and the number of large mirrors is 214. So the number of non - medium mirrors is (102 + 214=316). Then the total number of medium mirrors is (480-(102 + 214)=164).

Step2: Calculate broken medium mirrors

We know that the number of non - broken medium mirrors is 96. Let the number of broken medium mirrors be (x). Since the total number of medium mirrors is the sum of broken and non - broken medium mirrors, we have (x+96 = 164). Solving for (x), we get (x=164 - 96=68).

Answer:

68
