If `6xx 5 = 64 , 8 xx 7 = 116 and 10 xx 7 = 144` then `11 xx 10 = ?`

Options

A. A. 224
B. B. 242
C. C. 243
D. D. 222

Answer

To solve the problem, we need to identify the pattern in the given equations and apply it to find the value of `11 xx 10`.

### Step-by-Step Solution:

1. **Identify the pattern**:
We have the following equations:
- \( 6 \times 5 = 64 \)
- \( 8 \times 7 = 116 \)
- \( 10 \times 7 = 144 \)

2. **Calculate the normal multiplication**:
- For \( 6 \times 5 \):
\[ 6 \times 5 = 30 \]
- For \( 8 \times 7 \):
\[ 8 \times 7 = 56 \]
- For \( 10 \times 7 \):
\[ 10 \times 7 = 70 \]

3. **Determine how to reach the results**:
- For \( 6 \times 5 = 30 \) to reach \( 64 \):
\[ 30 \times 2 + 4 = 60 + 4 = 64 \]
- For \( 8 \times 7 = 56 \) to reach \( 116 \):
\[ 56 \times 2 + 4 = 112 + 4 = 116 \]
- For \( 10 \times 7 = 70 \) to reach \( 144 \):
\[ 70 \times 2 + 4 = 140 + 4 = 144 \]

4. **Apply the same pattern to \( 11 \times 10 \)**:
- First, calculate \( 11 \times 10 \):
\[ 11 \times 10 = 110 \]
- Now, apply the identified pattern:
\[ 110 \times 2 + 4 = 220 + 4 = 224 \]

5. **Final answer**:
Therefore, \( 11 \times 10 = 224 \).

### Conclusion:
The value of \( 11 \times 10 \) is \( 224 \).
