If '*' represents 12, '@' represents 48. '$' represents 24, zod 'l' represents 6, then what mathematical equation below will be equal to 90?

Options

A. `**+$div "@"-!`
B. `**div!+$xx"@"`
C. `Sdiv**xx"@"-!`
D. `Sxx"@"-!xx**`

Answer

To solve the problem, we need to substitute the symbols with their respective numerical values and check which mathematical equation equals 90.

Given:
- '*' represents 12
- '@' represents 48
- '$' represents 24
- 'l' represents 6

We will check each option one by one to find the equation that equals 90.

### Step 1: Check the first equation
Assuming the first equation is:
\[ * + $ / @ - l \]

Substituting the values:
\[ 12 + 24 / 48 - 6 \]

Now, perform the operations:
1. Calculate \( 24 / 48 = 0.5 \)
2. Now substitute back:
\[ 12 + 0.5 - 6 \]
3. Calculate \( 12 + 0.5 = 12.5 \)
4. Finally, \( 12.5 - 6 = 6.5 \)

**Result:** This does not equal 90.

### Step 2: Check the second equation
Assuming the second equation is:
\[ * / l + $ + @ \]

Substituting the values:
\[ 12 / 6 + 24 + 48 \]

Now, perform the operations:
1. Calculate \( 12 / 6 = 2 \)
2. Now substitute back:
\[ 2 + 24 + 48 \]
3. Calculate \( 2 + 24 = 26 \)
4. Finally, \( 26 + 48 = 74 \)

**Result:** This does not equal 90.

### Step 3: Check the third equation
Assuming the third equation is:
\[ $ / @ * @ - l \]

Substituting the values:
\[ 24 / 12 * @ - l \]

Now, perform the operations:
1. Calculate \( 24 / 12 = 2 \)
2. Substitute back:
\[ 2 * 48 - 6 \]
3. Calculate \( 2 * 48 = 96 \)
4. Finally, \( 96 - 6 = 90 \)

**Result:** This equals 90.

### Conclusion
The correct equation that equals 90 is:
\[ $ / @ * @ - l \]
or in numerical terms:
\[ 24 / 12 * 48 - 6 \]
