Options

A. a. 24
B. b. 20
C. c. 15
D. d. 10

Answer

To solve the expression \( 4.999 + 1.999 \times 6.001 \) using approximation, we can follow these steps:

### Step 1: Approximate the Numbers
We start by approximating the numbers involved in the expression:
- \( 4.999 \) can be approximated to \( 5 \)
- \( 1.999 \) can be approximated to \( 2 \)
- \( 6.001 \) can be approximated to \( 6 \)

### Step 2: Rewrite the Expression
Now, we can rewrite the expression using these approximated values:
\[ 5 + 2 \times 6 \]

### Step 3: Perform the Multiplication
According to the order of operations (BODMAS/BIDMAS), we first perform the multiplication:
\[ 2 \times 6 = 12 \]

### Step 4: Perform the Addition
Now, we add the result of the multiplication to the approximated value of \( 4.999 \):
\[ 5 + 12 = 17 \]

### Final Answer
Thus, the approximate value of \( 4.999 + 1.999 \times 6.001 \) is:
\[ \boxed{17} \]
