In the following question a specific group of numbers is given. From the given alternatives, find out the right number which matches the given group.
341, 572, 781

Options

A. 634
B. 891
C. 909
D. 990

Answer

To solve the problem, we need to identify the pattern in the given numbers: 341, 572, and 781.

### Step-by-Step Solution:

1. **Identify the Pattern**:
- For the number 341:
- The first digit is 3 and the last digit is 1.
- The sum of the first and last digits: \(3 + 1 = 4\).
- The middle digit is 4, which matches our calculation.

2. **Check the Next Number**:
- For the number 572:
- The first digit is 5 and the last digit is 2.
- The sum of the first and last digits: \(5 + 2 = 7\).
- The middle digit is 7, which matches our calculation.

3. **Check the Third Number**:
- For the number 781:
- The first digit is 7 and the last digit is 1.
- The sum of the first and last digits: \(7 + 1 = 8\).
- The middle digit is 8, which matches our calculation.

4. **Finding the Correct Option**:
- Now we need to find a number from the options that follows the same pattern.
- Let's analyze each option:
- **Option 1: 6, 3, 10**
- \(6 + 10 = 16\) (middle digit should be 16, which is incorrect).
- **Option 2: 8, 9, 1**
- \(8 + 1 = 9\) (middle digit is 9, which is correct).
- **Option 3: 9, 0, 9**
- \(9 + 9 = 18\) (middle digit should be 18, which is incorrect).
- **Option 4: 9, 9, 0**
- \(9 + 0 = 9\) (middle digit is 9, which is correct).

5. **Conclusion**:
- The options that match the pattern are Option 2 (8, 9, 1) and Option 4 (9, 9, 0).

### Final Answer:
The correct numbers that match the given group are Option 2 and Option 4.
