If we interchange the value of + and ÷ then find the value of given expression? 27 ÷ 3 − 18 + 3 × 2 = ?

Options

A. 12
B. 15
C. 18
D. 21

Answer

To solve the given expression after interchanging the operations of addition (+) and division (÷), we will follow these steps:

### Step-by-Step Solution:

1. **Write the Original Expression**:
The original expression is:
\[ 27 \div 3 - 18 + 3 \times 2 \]

2. **Interchange the Operations**:
We will replace division (÷) with addition (+) and addition (+) with division (÷). The modified expression becomes:
\[ 27 + 3 - 18 \div 3 \times 2 \]

3. **Evaluate the New Expression**:
According to the order of operations (BODMAS/BIDMAS), we will first perform the division:
\[ 18 \div 3 = 6 \]
Now, substitute this back into the expression:
\[ 27 + 3 - 6 \times 2 \]

4. **Continue with Multiplication**:
Next, we perform the multiplication:
\[ 6 \times 2 = 12 \]
Substitute this back into the expression:
\[ 27 + 3 - 12 \]

5. **Perform Addition and Subtraction**:
Now, we will perform the addition and subtraction from left to right:
\[ 27 + 3 = 30 \]
Then subtract:
\[ 30 - 12 = 18 \]

6. **Final Result**:
The final value of the modified expression is:
\[ 18 \]

### Final Answer:
The value of the expression after interchanging the operations is **18**.
