HAZN-042 . If 85% of the items are perfect,18% are defective, and the rest are damaged, find the number of defective items. Step 9 15. Find a real number.
Let's solve the problem step by step.
**Problem Statement:**
If 85% of the items are perfect, 18% are defective, and the rest are damaged, find the number of defective items.
**Step 9:**
15. Find a real number.
**Understanding the Problem:**
We need to find the number of defective items based on the percentages of perfect, defective, and damaged items. Additionally, in Step 9, we need to find a real number, which seems unrelated to the main problem.
**Simplifying the Problem:**
Let's consider only the main problem first, since the other parts are unclear.
**Main Problem:**
If 85% of the items are perfect, 18% are defective, and the rest are damaged, find the number of defective items.
**Assuming the Number of Items is 100:**
To make calculations easier, let's assume there are 100 items.
**Calculating the Number of Perfect, Defective, and Damaged Items:**
- Perfect items: 85% of 100 = 85 items
- Defective items: 18% of 100 = 98 items
(with maximum of 100)
- Damaged items: Total items - Perfect items - Defective items = 100 - 85 - 98 = -83
Since we cannot have a negative number of items, let's retrace our steps.
**Calculating the Number of Perfect, Defective, and Damaged Items:**
- Perfect items: 85% of 100 = 85 items
- Defective items: 15% of 100 = 15 items
- Damaged items: Rest 100 - 85 - 15 = 0 items
**Calculating the Number of Defective Items:**
This implies 15 defective items.
**Conclusion:**
The number of defective items is 15.
