B. 1320
C. 1240
D. 1120

Answer

To solve the equation \( 48\% \text{ of } 840 = 36\% \text{ of } ? \), we can follow these steps:

### Step 1: Convert percentages to fractions
We start by converting the percentages into fractions:
- \( 48\% = \frac{48}{100} \)
- \( 36\% = \frac{36}{100} \)

### Step 2: Set up the equation
Now we can rewrite the equation:
\[ \frac{48}{100} \times 840 = \frac{36}{100} \times ? \]

### Step 3: Eliminate the denominators
We can eliminate the denominators by multiplying both sides of the equation by 100:
\[ 48 \times 840 = 36 \times ? \]

### Step 4: Calculate \( 48 \times 840 \)
Now we calculate \( 48 \times 840 \):
\[ 48 \times 840 = 40320 \]

### Step 5: Rewrite the equation
Now we can rewrite the equation as:
\[ 40320 = 36 \times ? \]

### Step 6: Solve for \( ? \)
To find \( ? \), we divide both sides by 36:
\[ ? = \frac{40320}{36} \]

### Step 7: Perform the division
Now we perform the division:
\[ ? = 1120 \]

### Final Answer
Thus, the value that should come in place of the question mark is:
\[ \boxed{1120} \]
