What will come in the place of '_____' in the Eight Thousand + Seven Ones + _____ Tens = 8087?

Options

A. 8
B. 10
C. 7
D. 80

Answer

To solve the problem, we need to find the value that will replace the blank in the equation:

**Eight Thousand + Seven Ones + _____ Tens = 8087**

1. **Understanding the components**:
- Eight Thousand is represented as 8000.
- Seven Ones is represented as 7.
- The unknown value in Tens can be represented as \( x \times 10 \), where \( x \) is the value we need to find.

2. **Setting up the equation**:
- We can write the equation as:
\[ 8000 + 7 + (x \times 10) = 8087 \]

3. **Simplifying the equation**:
- Combine the known values:
\[ 8000 + 7 = 8007 \]
- Now, substitute this back into the equation:
\[ 8007 + (x \times 10) = 8087 \]

4. **Isolating the unknown**:
- To find \( x \), subtract 8007 from both sides:
\[ (x \times 10) = 8087 - 8007 \]
- Calculate the right side:
\[ (x \times 10) = 80 \]

5. **Finding the value of \( x \)**:
- Now, divide both sides by 10:
\[ x = \frac{80}{10} = 8 \]

Thus, the value that comes in place of '_____' is **8**.
