1000000 is obtained, when a number is subtracted from the sum of 893645 and 635489, find that number.

Options

A. 106355
B. 364511
C. 51329
D. 529134

Answer

To solve the problem step by step, we need to follow these instructions:

### Step 1: Add the two numbers
We need to calculate the sum of 893645 and 635489.

\[ \begin{array}{r} 893645 \\ + 635489 \\ \hline \end{array} \]

Let's add them column by column:

1. **Units place**: \(5 + 9 = 14\) (write 4, carry over 1)
2. **Tens place**: \(4 + 8 + 1 = 13\) (write 3, carry over 1)
3. **Hundreds place**: \(6 + 4 + 1 = 11\) (write 1, carry over 1)
4. **Thousands place**: \(3 + 5 + 1 = 9\) (write 9)
5. **Ten-thousands place**: \(9 + 3 = 12\) (write 2, carry over 1)
6. **Hundred-thousands place**: \(8 + 6 + 1 = 15\) (write 5, carry over 1)

So, the total sum is:

\[ \begin{array}{r} 893645 \\ + 635489 \\ \hline 1523134 \\ \end{array} \]

### Step 2: Set up the equation
According to the problem, when a number \(x\) is subtracted from the sum \(1523134\), we get \(1000000\). Therefore, we can set up the equation:

\[ 1523134 - x = 1000000 \]

### Step 3: Solve for \(x\)
To find \(x\), we can rearrange the equation:

\[ x = 1523134 - 1000000 \]

Now, let's perform the subtraction:

\[ 1523134 - 1000000 = 523134 \]

### Conclusion
The number that needs to be subtracted is **523134**.
