Choose the odd one from the given four choices.

Options

A. `6:16`
B. `7:19`
C. `10:27`
D. `11:31`

Explanation

To solve the problem of choosing the odd one out from the given options, we will analyze the relationship between the pairs of numbers in each option.

### Step-by-Step Solution:

1. **Identify the Options:**
- Option 1: 6 is to 16
- Option 2: 7 is to 19
- Option 3: 10 is to 27
- Option 4: 11 is to 31

2. **Establish a Pattern:**
We will check if there is a consistent mathematical relationship between the first and second numbers in each pair. A potential pattern to explore is multiplying the first number by 3 and then subtracting 2.

3. **Check Option 1:**
- First number: 6
- Calculation: \(3 \times 6 - 2 = 18 - 2 = 16\)
- Result: This matches the second number (16).

4. **Check Option 2:**
- First number: 7
- Calculation: \(3 \times 7 - 2 = 21 - 2 = 19\)
- Result: This matches the second number (19).

5. **Check Option 3:**
- First number: 10
- Calculation: \(3 \times 10 - 2 = 30 - 2 = 28\)
- Result: This does NOT match the second number (27).

6. **Check Option 4:**
- First number: 11
- Calculation: \(3 \times 11 - 2 = 33 - 2 = 31\)
- Result: This matches the second number (31).

7. **Conclusion:**
From the analysis, options 1, 2, and 4 follow the established pattern of \(3 \times \text{first number} - 2 = \text{second number}\). However, option 3 does not follow this pattern. Therefore, the odd one out is **Option 3: 10 is to 27**.
