Study the following pattern
`9xx9+7=88`
`98xx9+6=888`,
`987xx9+5=8888`, ……………
What is value of `987654xx9+2` ?

Options

A. 88888
B. 888888
C. 8888888
D. 8898988

Explanation

To solve the problem, we need to identify the pattern in the given equations and apply it to find the value of `987654xx9 + 2`.

### Step-by-Step Solution:

1. **Identify the Pattern**:
- The first equation is `9xx9 + 7 = 88`.
- The second equation is `98xx9 + 6 = 888`.
- The third equation is `987xx9 + 5 = 8888`.

From these equations, we can observe that:
- The number of digits before the `9` is increasing by 1 in each equation (1 digit, 2 digits, 3 digits).
- The number added is decreasing by 1 each time (7, 6, 5).
- The result is increasing in the number of digits as well (2 digits, 3 digits, 4 digits), and the last digit of the result appears to be `8`.

2. **Formulate the Next Equation**:
- Following the established pattern, the next equation will be `987654xx9 + 2`.
- Here, the number of digits before `9` is 6, and the number added is 2.

3. **Determine the Result**:
- Since the previous results had a pattern of increasing the number of digits in the result, we can predict:
- The result of `987654xx9 + 2` should have 7 digits.
- The last digit of the result will also be `8`, as seen in the previous equations.
- Therefore, the result will be `8888888` (7 times `8`).

4. **Final Calculation**:
- Thus, the value of `987654xx9 + 2` is `8888888`.

### Final Answer:
The value of `987654xx9 + 2` is **8888888**.
