If 40038 = 38 ones + 38 thousand +......... tens. Then, the number in the blank space is

Options

A. 380
B. 38
C. 138
D. 200

Answer

To solve the problem, we need to express the number 40038 in terms of its place values and find the missing value that corresponds to the tens place.

### Step-by-Step Solution:

1. **Understanding the Number**:
The number 40038 can be broken down into its place values:
- 40000 (which is 40 thousands)
- 0000 (which is 0 hundreds)
- 030 (which is 3 tens)
- 8 (which is 8 ones)

2. **Writing the Equation**:
According to the question, we can express 40038 as:
\[ 40038 = 38 \text{ ones} + 38000 + \text{(some value for tens)} \]
We can denote the unknown value for the tens place as \(x\).

3. **Setting Up the Equation**:
We can write the equation as:
\[ 40038 = 38 \times 1 + 38000 + x \times 10 \]
This simplifies to:
\[ 40038 = 38 + 38000 + 10x \]

4. **Combining Like Terms**:
Now, we combine the known values:
\[ 40038 = 38038 + 10x \]

5. **Isolating the Variable**:
To find \(10x\), we subtract 38038 from both sides:
\[ 10x = 40038 - 38038 \]
\[ 10x = 2000 \]

6. **Solving for \(x\)**:
Now, we divide both sides by 10 to solve for \(x\):
\[ x = \frac{2000}{10} = 200 \]

7. **Conclusion**:
The value in the blank space that corresponds to the tens place is 200.

### Final Answer:
The number in the blank space is **200**.
