Some questions are solved on the basis of certain patter. On the same basis find out the correct answer for the unsolved equation.
`7xx5xx4=57354,8xx7xx3=78563` then `6xx8xx5=?`

Options

A. 86585
B. 86855
C. 68485
D. 86485

Explanation

To solve the equation `6xx8xx5=?` based on the provided patterns from the previous equations, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Pattern**:
- From the first equation `7xx5xx4=57354`, we observe:
- The first two digits are `7` and `5`. When reversed, they become `5` and `7`.
- The middle term is the product of the first two digits: \( 7 \times 5 = 35 \).
- The last digit remains the same, which is `4`.
- Thus, the result is formed as `5 (reversed) + 7 (reversed) + 35 (product) + 4 (last digit)`, which gives `57354`.

2. **Apply the Same Pattern**:
- For the second equation `8xx7xx3=78563`, we see:
- The first two digits `8` and `7` when reversed become `7` and `8`.
- The middle term is the product: \( 8 \times 7 = 56 \).
- The last digit remains `3`.
- Therefore, the result is `7 (reversed) + 8 (reversed) + 56 (product) + 3 (last digit)`, which gives `78563`.

3. **Now Solve for `6xx8xx5`**:
- The first two digits are `6` and `8`. When reversed, they become `8` and `6`.
- Calculate the middle term: \( 6 \times 8 = 48 \).
- The last digit remains `5`.
- Therefore, the result will be formed as `8 (reversed) + 6 (reversed) + 48 (product) + 5 (last digit)`.

4. **Combine the Results**:
- Putting it all together, we have:
- First digit: `8`
- Second digit: `6`
- Middle term: `48`
- Last digit: `5`
- Thus, the final result is `86485`.

### Final Answer:
`6xx8xx5 = 86485`
