Answer

To solve the equation \( 59.98\% \text{ of } 599.85 \times 0.801 + 92 = ? \), we will use approximate values for simplification.

### Step-by-Step Solution:

1. **Convert Percentage to Decimal:**
\[ 59.98\% \approx 60\% \]
This means we can treat \( 59.98\% \) as \( 0.60 \).

**Hint:** When dealing with percentages, rounding to the nearest whole number can simplify calculations.

2. **Calculate the Approximate Value of 599.85:**
\[ 599.85 \approx 600 \]
This simplifies our multiplication.

**Hint:** Rounding numbers to the nearest hundred or ten can make calculations easier.

3. **Approximate the Value of 0.801:**
\[ 0.801 \approx 0.8 \]
This will help in simplifying the multiplication further.

**Hint:** When dealing with decimals, rounding to one decimal place can often suffice for approximation.

4. **Calculate \( 60\% \text{ of } 600 \):**
\[ 60\% \text{ of } 600 = 0.60 \times 600 = 360 \]

**Hint:** To find a percentage of a number, multiply the decimal form of the percentage by the number.

5. **Multiply by the Approximate Value of 0.801:**
\[ 360 \times 0.8 = 288 \]

**Hint:** When multiplying by decimals, consider breaking it down (e.g., \( 360 \times 0.8 = 360 \times \frac{8}{10} \)).

6. **Add 92 to the Result:**
\[ 288 + 92 = 380 \]

**Hint:** Always ensure to add the final constant after all multiplications are done.

7. **Final Result:**
The approximate value that should come in place of the question mark is:
\[ ? \approx 380 \]

### Conclusion:
Thus, the answer is \( 380 \).
