यदि + का अर्थ ÷, × का अर्थ - हो, - का अर्थ × और ÷ का अर्थ + हो, तो 38+19-16×17÷3=?

Options

A. 16
B. 19
C. 18
D. 12

Answer

To solve the equation \( 38 + 19 - 16 \times 17 \div 3 \) with the given meanings of the operations, we first need to replace each operation with its new meaning:

- \( + \) means \( \div \)
- \( - \) means \( \times \)
- \( \times \) means \( - \)
- \( \div \) means \( + \)

Now, let's rewrite the equation with the new meanings:

1. Replace \( + \) with \( \div \):
\[ 38 \div 19 - 16 \times 17 \div 3 \rightarrow 38 \div 19 \]

2. Replace \( - \) with \( \times \):
\[ 38 \div 19 \times 16 \times 17 \div 3 \]

3. Replace \( \times \) with \( - \):
\[ 38 \div 19 \div 16 - 17 \div 3 \]

4. Replace \( \div \) with \( + \):
\[ 38 + 19 + 16 - 17 + 3 \]

Now, we will perform the operations step by step:

### Step 1: Calculate \( 38 \div 19 \)
\[ 38 \div 19 = 2 \]

### Step 2: Calculate \( 2 \times 16 \)
\[ 2 \times 16 = 32 \]

### Step 3: Calculate \( 32 \times 17 \)
\[ 32 \times 17 = 544 \]

### Step 4: Calculate \( 544 \div 3 \)
\[ 544 \div 3 \approx 181.33 \]

### Final Calculation
Now we combine the results:
\[ 2 \times 16 - 544 \div 3 = 32 - 181.33 = -149.33 \]

Thus, the final answer is:
\[ \text{Answer} = -149.33 \]
