Choose one number which is similar to the numbers in the given set of three numbers.
Given set : 363, 489, 579

Options

A. 562
B. 471
C. 382
D. 281

Explanation

To solve the problem, we need to find a number from the given options that has a similar pattern to the numbers in the set: 363, 489, and 579. The pattern involves calculating the sum of the digits of each number and then reducing that sum to a single digit.

### Step-by-Step Solution:

1. **Calculate the sum of the digits for each number in the given set:**
- For **363**:
\[ 3 + 6 + 3 = 12 \]
Now, reduce 12 to a single digit:
\[ 1 + 2 = 3 \]

- For **489**:
\[ 4 + 8 + 9 = 21 \]
Now, reduce 21 to a single digit:
\[ 2 + 1 = 3 \]

- For **579**:
\[ 5 + 7 + 9 = 21 \]
Now, reduce 21 to a single digit:
\[ 2 + 1 = 3 \]

All three numbers in the set reduce to the single digit **3**.

2. **Now, check each option to see which one also reduces to 3:**
- **Option 1: 562**
\[ 5 + 6 + 2 = 13 \]
Reduce 13:
\[ 1 + 3 = 4 \quad (\text{not equal to } 3) \]

- **Option 2: 471**
\[ 4 + 7 + 1 = 12 \]
Reduce 12:
\[ 1 + 2 = 3 \quad (\text{equal to } 3) \]

- **Option 3: 382**
\[ 3 + 8 + 2 = 13 \]
Reduce 13:
\[ 1 + 3 = 4 \quad (\text{not equal to } 3) \]

- **Option 4: 281**
\[ 2 + 8 + 1 = 11 \]
Reduce 11:
\[ 1 + 1 = 2 \quad (\text{not equal to } 3) \]

3. **Conclusion:**
The only option that reduces to the same single digit (3) as the numbers in the set is **Option 2: 471**.

### Final Answer:
**Option 2: 471**
