Choose the number pair/group which is different from others.

Options

A. 3,9,6,15
B. 6,18,12,30
C. 4,16,12,24
D. 12,36,24,60

Explanation

To solve the question of identifying the number pair/group that is different from the others, we will analyze each group of numbers to find a common pattern.

### Step-by-Step Solution:

1. **Analyze the First Group: 3, 9, 6, 15**
- We can express these numbers as multiples of 3:
- \(3 \times 1 = 3\)
- \(3 \times 3 = 9\)
- \(3 \times 2 = 6\)
- \(3 \times 5 = 15\)
- The order of multipliers is: 1, 3, 2, 5.

2. **Analyze the Second Group: 6, 18, 12, 30**
- We can express these numbers as multiples of 6:
- \(6 \times 1 = 6\)
- \(6 \times 3 = 18\)
- \(6 \times 2 = 12\)
- \(6 \times 5 = 30\)
- The order of multipliers is: 1, 3, 2, 5.

3. **Analyze the Third Group: 4, 16, 12, 24**
- We can express these numbers as multiples of 4:
- \(4 \times 1 = 4\)
- \(4 \times 4 = 16\)
- \(4 \times 3 = 12\)
- \(4 \times 6 = 24\)
- The order of multipliers is: 1, 4, 3, 6. (This is different from the previous groups.)

4. **Analyze the Fourth Group: 12, 36, 24, 60**
- We can express these numbers as multiples of 12:
- \(12 \times 1 = 12\)
- \(12 \times 3 = 36\)
- \(12 \times 2 = 24\)
- \(12 \times 5 = 60\)
- The order of multipliers is: 1, 3, 2, 5.

5. **Conclusion:**
- The first, second, and fourth groups follow the same pattern of multipliers: 1, 3, 2, 5.
- The third group has a different order of multipliers: 1, 4, 3, 6.
- Therefore, the group that is different from the others is **the third group: 4, 16, 12, 24**.
