C. 2.03
D. 1.02

Answer

To solve the equation \( \frac{11882}{42 \times 7 \times ?} = 20 \), we will follow these steps:

### Step 1: Rewrite the equation
We start with the equation:
\[ \frac{11882}{42 \times 7 \times X} = 20 \]
where \( X \) is the unknown we need to find.

### Step 2: Cross-multiply
To eliminate the fraction, we can cross-multiply:
\[ 11882 = 20 \times (42 \times 7 \times X) \]

### Step 3: Calculate \( 42 \times 7 \)
First, we need to calculate \( 42 \times 7 \):
\[ 42 \times 7 = 294 \]
Now substitute this back into the equation:
\[ 11882 = 20 \times (294 \times X) \]

### Step 4: Simplify the equation
Now we can simplify the right side:
\[ 11882 = 5880 \times X \]
where \( 5880 = 20 \times 294 \).

### Step 5: Solve for \( X \)
To find \( X \), we divide both sides by 5880:
\[ X = \frac{11882}{5880} \]

### Step 6: Perform the division
Now we perform the division:
\[ X = 2.02 \]

### Step 7: Conclusion
Thus, the value of \( ? \) or \( X \) is approximately \( 2.02 \).
