Options

A. 9
B. 11
C. 13
D. 10

Explanation

To solve the equation \( 1960 \div (x \times 4) = 49 \), we will follow these steps:

### Step 1: Rewrite the equation
We start with the equation:
\[ 1960 \div (x \times 4) = 49 \]

### Step 2: Multiply both sides by \( (x \times 4) \)
To eliminate the division, we multiply both sides by \( (x \times 4) \):
\[ 1960 = 49 \times (x \times 4) \]

### Step 3: Simplify the right side
Now we can simplify the right side:
\[ 1960 = 49 \times 4x \]

### Step 4: Calculate \( 49 \times 4 \)
Calculate \( 49 \times 4 \):
\[ 49 \times 4 = 196 \]
So, we can rewrite the equation as:
\[ 1960 = 196x \]

### Step 5: Divide both sides by 196
Next, we divide both sides by 196 to isolate \( x \):
\[ x = \frac{1960}{196} \]

### Step 6: Calculate \( \frac{1960}{196} \)
Now we perform the division:
\[ x = 10 \]

### Final Answer
Thus, the value of \( x \) is:
\[ \boxed{10} \]
