Options

A. 42
B. 39
C. 74
D. 60

Explanation

To solve the problem step by step, let's break it down:

### Step 1: Understand the Equation
We need to solve for the question mark (let's denote it as \( x \)) in the equation:
\[ x\% \text{ of } \left( \frac{5284.89}{7.08} \right) = 1986.01 - 1533.06 \]

### Step 2: Calculate the Right Side
First, we calculate the right side of the equation:
\[ 1986.01 - 1533.06 = 452.95 \]

### Step 3: Calculate the Left Side
Next, we calculate the left side:
\[ \frac{5284.89}{7.08} \]
Performing the division:
\[ 5284.89 \div 7.08 \approx 746.45 \]

### Step 4: Set Up the Equation
Now we can set up the equation using the values we calculated:
\[ \frac{x}{100} \times 746.45 = 452.95 \]

### Step 5: Solve for \( x \)
To isolate \( x \), we multiply both sides by 100 and then divide by 746.45:
\[ x = \frac{452.95 \times 100}{746.45} \]

### Step 6: Calculate \( x \)
Now we perform the multiplication and division:
\[ x \approx \frac{45295}{746.45} \approx 60.6 \]

### Step 7: Round \( x \)
Since we are looking for a percentage, we round \( x \) to the nearest whole number:
\[ x \approx 61 \]

### Step 8: Conclusion
Thus, the value of the question mark is approximately:
\[ \text{Question Mark} = 61\% \]
