Question - Calculating Percentage of Discarded Wafers due to Breakage in January
Solution:
In the provided image, we're presented with data showing the causes for discarded wafers in January, along with question 33, which asks for the percentage of discarded wafers due to breakage.Let's first identify the number of wafers discarded due to breakage: it's 10.Next, we'll find the total number of discarded wafers: it's 34.To calculate the percentage of discarded wafers due to breakage, we need to divide the number of wafers broken by the total number discarded and then multiply by 100 to get the percentage:Percentage = (Number of wafers broken / Total number discarded) × 100Percentage = (10 / 34) × 100Now, doing the math:Percentage = 0.2941... × 100Percentage ≈ 29.41%Rounding this to a whole number gives us approximately 29%, which matches option B in the image. Therefore, the percentage of the discarded wafers that was due to breakage is approximately 29%.
