Detailed Explanation & Answer
### Step 1: Given Information
Mean of **x, y, z** is **K**.

So,
(x + y + z) / 3 = K
=> x + y + z = 3K

We need to find the mean of **x/y, 1, z/y**.

### Step 2: Compute the Mean
Mean = (x/y + 1 + z/y) / 3

Rewriting:
= [(x + y + z) / y] / 3
= (3K / y) / 3
= K / y

### Final Answer:
**(2) K/y**
### चरण 1: दी गई जानकारी
**x, y, z** का माध्य **K** है।

तो,
(x + y + z) / 3 = K
=> x + y + z = 3K

हमें **x/y, 1, z/y** का माध्य ज्ञात करना है।

### चरण 2: माध्य की गणना करें
माध्य = (x/y + 1 + z/y) / 3

पुनर्लेखन:
= [(x + y + z) / y] / 3
= (3K / y) / 3
= K / y

### अंतिम उत्तर:
**(2) K/y**
