If the mathermatical operators `-,+xxanddiv` are represented by A,B,C and D respectively ,then find the value of 9 B 20 C 12 D 6 A 5 .

Options

A. 40
B. 49
C. 57
D. 41

Answer

To solve the expression \( 9B20C12D6A5 \) where the operators are represented as follows:
- A = minus (-)
- B = plus (+)
- C = multiply (×)
- D = divide (÷)

We can rewrite the expression using standard mathematical operators:

\[ 9 + 20 \times 12 \div 6 - 5 \]

Now, we will follow the order of operations, commonly known as BODMAS/BIDMAS (Brackets, Orders, Division and Multiplication, Addition and Subtraction).

### Step-by-Step Solution:

1. **Identify the operations**: The expression consists of addition, multiplication, division, and subtraction.

2. **Perform Division and Multiplication first**:
- Calculate \( 20 \times 12 \):
\[ 20 \times 12 = 240 \]
- Now replace \( 20C12 \) with \( 240 \):
\[ 9 + 240 \div 6 - 5 \]
- Next, calculate \( 240 \div 6 \):
\[ 240 \div 6 = 40 \]
- Now replace \( 240D6 \) with \( 40 \):
\[ 9 + 40 - 5 \]

3. **Perform Addition and Subtraction**:
- First, calculate \( 9 + 40 \):
\[ 9 + 40 = 49 \]
- Now replace \( 9 + 40 \) with \( 49 \):
\[ 49 - 5 \]
- Finally, calculate \( 49 - 5 \):
\[ 49 - 5 = 44 \]

Thus, the final answer is:

\[ \boxed{44} \]
