Approximate Equation Calculation

The question asks for the approximate value of '?' in the given equation. We can simplify the calculation by approximating the numbers.

The equation is:

$(44.97\% \text{ of } 226) + (55.03 \times 4.98) - ? = 140$

Approximating Values

• 44.97% is approximately 45%.
• 226 is approximately 225 (for easier percentage calculation) or simply use 226. Let's use 226 for better accuracy while keeping the percentage simple. So, 45% of 226.
• 55.03 is approximately 55.
• 4.98 is approximately 5.
• 140 is already a round number.

Step-by-Step Calculation

1. Calculate the first term (percentage):

   Approximate 44.97% of 226 $\approx 45\%$ of $226$

   $ \frac{45}{100} \times 226 = 0.45 \times 226 $

   $ 0.45 \times 226 = 101.7 $

2. Calculate the second term (product):

   Approximate 55.03 $\times$ 4.98 $\approx 55 \times 5$

   $ 55 \times 5 = 275 $

3. Substitute the approximate values back into the equation:

   $ 101.7 + 275 - ? = 140 $

4. Simplify the equation:

   $ 376.7 - ? = 140 $

5. Solve for '?':

   $ ? = 376.7 - 140 $

   $ ? = 236.7 $

Identify Closest Option

The calculated approximate value for '?' is 236.7. Comparing this with the given options:

• Option 1: 25
• Option 2: 237
• Option 3: 508
• Option 4: 120

The value 236.7 is closest to 237.
