What approximate value should come in place of the question mark (?) in the expression 499.99 + 1999 ÷ 39.99 × 50.01, if you are required to estimate the value without calculating it exactly?

Introduction / Context:
This question involves estimating the value of an expression that includes division, multiplication, and addition with decimals. The goal is to find a good approximation that matches one of the provided options, a typical skill tested in competitive exams to save time during calculations.

Given Data / Assumptions:

• Expression: 499.99 + 1999 ÷ 39.99 × 50.01.
• We are allowed to approximate 499.99, 39.99 and 50.01 by nearby integers.
• The objective is a close but not exact numerical answer.

Concept / Approach:
Since 499.99 is very close to 500, 39.99 is very near 40, and 50.01 is essentially 50, we can replace these decimals with their closest integers. This simplifies the calculation dramatically: we first handle the division, then the multiplication, and finally the addition, in accordance with the correct order of operations.

Step-by-Step Solution:
Step 1: Approximate 499.99 ≈ 500. Step 2: Approximate 39.99 ≈ 40. Step 3: Approximate 50.01 ≈ 50. Step 4: Rewrite the expression with these approximations: 499.99 + 1999 ÷ 39.99 × 50.01 ≈ 500 + 1999 ÷ 40 × 50. Step 5: Perform the division first: 1999 ÷ 40 ≈ 50 (since 40 × 50 = 2000, which is very close). Step 6: Then multiply by 50: 50 × 50 = 2,500. Step 7: Finally add the approximate 500: 500 + 2,500 = 3,000. Step 8: Thus, the approximate value is about 3,000.

Verification / Alternative check:
Even if you are slightly more precise, 1999 ÷ 40 is 49.975, extremely close to 50, and using 49.975 × 50 gives roughly 2,498.75. Adding 500 yields around 2,998.75, which is still closest to 3,000 among the given options. Therefore, the approximation is robust and consistent with the exact arithmetic.

Why Other Options Are Wrong:
Options like 2,500 or 2,700 underestimate the result, since the multiplication term alone is around 2,500 and then you still add roughly 500 more. Options like 3,200 or 2,800 are not as close to the more accurate approximate total of about 3,000.

Common Pitfalls:
A common mistake is to round some numbers up and others down in a biased way that skews the result, or to accidentally change the order of operations. Always remember that division and multiplication take precedence over addition, and when approximating, keep the rounding consistent and moderate.

Final Answer:
The approximate value of the expression is 3,000.
