What would come in place of ($) mark in the following equation ?
`22 $ 20 div 156 = 145`

Options

A. 6
B. 2
C. 4
D. 0

Answer

To solve the equation \( 22 \$ 20 \div 156 = 145 \), we need to determine what operation or number should replace the dollar sign ($).

### Step-by-Step Solution:

1. **Understand the Equation**:
The equation can be interpreted as:
\[ 22 \$ 20 = 145 \times 156 \]
Here, we need to find the value of \( 22 \$ 20 \).

2. **Calculate the Right Side**:
First, we need to calculate \( 145 \times 156 \):
\[ 145 \times 156 = 22620 \]

3. **Set Up the Equation**:
Now we have:
\[ 22 \$ 20 = 22620 \]

4. **Determine the Operation**:
Since we need to find out what operation \( \$ \) represents, we can assume it is multiplication:
\[ 22 \times 20 = 440 \]
However, this does not equal 22620.

5. **Find the Missing Value**:
To find the missing value, we can rewrite the equation:
\[ 22 \$ 20 = 22620 \]
We can express \( \$ \) as:
\[ \$ = \frac{22620}{22} \]
Now, we can calculate:
\[ \$ = \frac{22620}{22} = 1020 \]

6. **Final Calculation**:
Now we need to check if \( 1020 \) can be expressed in terms of \( 20 \):
\[ 1020 = 20 \times 51 \]
This means that \( \$ \) could also represent multiplication by \( 51 \).

7. **Conclusion**:
The value that replaces \( \$ \) is \( 51 \).

### Final Answer:
The value that comes in place of \( \$ \) is \( 51 \).
