If `'gt'` stands for '-' , `'<'` stands for '+' , '=' stands for 'x' and '@' stands for `'div'` then what will be the value of `27 gt 81` @ `9 lt 6`
A. 27
B. 33
C. 30
D.24

Options

A. A
B. B
C. C
D. D

Answer

To solve the problem step by step, we will first translate the symbols into their respective mathematical operations based on the given definitions:

1. **Translation of Symbols**:
- `'gt'` stands for `-` (minus)
- `'<'` stands for `+` (plus)
- `'='` stands for `x` (multiplication)
- `'@'` stands for `div` (division)

Given the expression: `27 gt 81 @ 9 lt 6`

2. **Replacing Symbols**:
- Replace `gt` with `-`
- Replace `@` with `div`
- Replace `lt` with `+`

This gives us the expression:
\[ 27 - 81 \div 9 + 6 \]

3. **Applying BODMAS/BIDMAS Rules**:
According to the BODMAS/BIDMAS rules, we will perform the operations in the following order:
- Brackets
- Orders (i.e., powers and roots, etc.)
- Division and Multiplication (from left to right)
- Addition and Subtraction (from left to right)

4. **Step 1: Division**:
- Calculate \( 81 \div 9 \):
\[ 81 \div 9 = 9 \]

5. **Step 2: Substitute Back into the Expression**:
Now we substitute back into the expression:
\[ 27 - 9 + 6 \]

6. **Step 3: Perform Addition and Subtraction**:
- First, perform the subtraction:
\[ 27 - 9 = 18 \]
- Then, perform the addition:
\[ 18 + 6 = 24 \]

7. **Final Result**:
The final value is:
\[ \text{Value} = 24 \]

### Answer:
The correct answer is D. 24.
