724 - 336 + 499 = 775 + ?

Options

A. 110
B. 115
C. 120
D. None of these

Answer

To solve the equation \( 724 - 336 + 499 = 775 + ? \), we can follow these steps:

### Step 1: Simplify the left side of the equation
First, we need to perform the operations on the left side of the equation. According to the BODMAS rule, we will perform addition and subtraction from left to right.

1. Calculate \( 724 - 336 \):
\[ 724 - 336 = 388 \]

2. Now add \( 499 \) to the result:
\[ 388 + 499 = 887 \]

So, the left side simplifies to \( 887 \).

### Step 2: Set up the equation
Now we can rewrite the equation with the simplified left side:
\[ 887 = 775 + ? \]

### Step 3: Isolate the question mark
To find \( ? \), we need to isolate it on one side of the equation. We can do this by subtracting \( 775 \) from both sides:
\[ ? = 887 - 775 \]

### Step 4: Perform the subtraction
Now we will perform the subtraction:
\[ 887 - 775 = 112 \]

### Final Answer
Thus, the value of \( ? \) is \( 112 \).

Since \( 112 \) is not among the options provided (110, 115, 120, none of these), the correct answer is "none of these".
