The correct answer is
100
Approximate Equation Calculation
To find the approximate value of the expression $119.99 \div 14.99 \times 25.01 - 19.98 \times 4.96$, we first round the numbers to their nearest integers:
- $119.99 \approx 120$
- $14.99 \approx 15$
- $25.01 \approx 25$
- $19.98 \approx 20$
- $4.96 \approx 5$
Simplified Expression
Substitute these approximate values back into the equation:
$120 \div 15 \times 25 - 20 \times 5$
Applying BODMAS Rule
We follow the order of operations (BODMAS/PEMDAS): Brackets, Orders, Division/Multiplication (left-to-right), Addition/Subtraction (left-to-right).
- Division: $120 \div 15 = 8$
- First Multiplication: $8 \times 25 = 200$
- Second Multiplication: $20 \times 5 = 100$
- Subtraction: $200 - 100 = 100$
Final Result
The approximate value of the given expression is 100.
This matches Option D.
