यदि `6xx9xx3 =963 and 4xx 8xx5= 845` और `4 xx 8xx5 = 845,` तो `9xx4xx7 = ?`

Options

A. 974
B. 479
C. 497
D. 749

Explanation

To solve the problem, we need to identify the pattern in the given equations and apply it to the new equation.

### Step-by-step Solution:

1. **Understand the Pattern**:
- From the first equation, `6xx9xx3 = 963`, we can see that:
- The first digit (6) moves to the second position.
- The second digit (9) moves to the first position.
- The last digit (3) stays in the third position.
- This gives us the arrangement:
- 9 (1st) → 6 (2nd) → 3 (3rd) = 963.

2. **Apply the Same Pattern to the Second Equation**:
- From the second equation, `4xx8xx5 = 845`, we see:
- The first digit (4) moves to the second position.
- The second digit (8) moves to the first position.
- The last digit (5) stays in the third position.
- This gives us the arrangement:
- 8 (1st) → 4 (2nd) → 5 (3rd) = 845.

3. **Identify the Pattern for the New Equation**:
- Now we need to apply this pattern to `9xx4xx7`.
- According to the established pattern:
- The first digit (9) will move to the second position.
- The second digit (4) will move to the first position.
- The last digit (7) will stay in the third position.

4. **Construct the Answer**:
- Following the pattern:
- 4 (1st) → 9 (2nd) → 7 (3rd) = 497.

5. **Final Answer**:
- Therefore, `9xx4xx7 = 497`.
