`526xx12+188=50xx?`

Options

A. 120
B. 160
C. 140
D. None of these

Explanation

To solve the equation \( 526 \times 12 + 188 = 50 \times ? \), we will follow these steps:

### Step 1: Calculate \( 526 \times 12 \)
First, we need to multiply 526 by 12.

\[ 526 \times 12 = 6312 \]

### Step 2: Add 188 to the result
Next, we add 188 to the result obtained from the multiplication.

\[ 6312 + 188 = 6500 \]

### Step 3: Set up the equation
Now, we can set up the equation based on the original problem:

\[ 6500 = 50 \times ? \]

### Step 4: Solve for ?
To find the value of the question mark (?), we divide both sides of the equation by 50.

\[ ? = \frac{6500}{50} \]

### Step 5: Perform the division
Now we perform the division:

\[ ? = 130 \]

### Final Answer
Thus, the value of the question mark is:

\[ ? = 130 \]
