Which of the following group of alternative signs will make the equation correct, if they are put in between them?
निम्नलिखित विकल्पों में चिह्नों का कौन-सा समूह समीकरण में रखने पर समीकरण सत्य होगा?
6 * 4* 9* 15

Options

A. `xx,=,-`
B. `xx,-,=`
C. `=,xx,-`
D. `-,xx,=`

Explanation

To solve the problem, we need to determine which group of alternative signs will make the equation correct when placed between the numbers 6, 4, 9, and 15. We will evaluate each option step by step.

### Given Equation:
6 ___ 4 ___ 9 ___ 15

### Options to Evaluate:
1. Multiply, Equals, Minus
2. Multiply, Minus, Equals, Equals
3. Equals, Minus, Multiply, Minus
4. Minus, Multiply, Equals

### Step 1: Evaluate Option 1 (Multiply, Equals, Minus)
- Substitute the operators:
\[ 6 \times 4 = 9 - 15 \]
- Calculate:
\[ 6 \times 4 = 24 \]
\[ 9 - 15 = -6 \]
- Check if \( 24 = -6 \): **False** (This option is incorrect)

### Step 2: Evaluate Option 2 (Multiply, Minus, Equals, Equals)
- Substitute the operators:
\[ 6 \times 4 - 9 = 15 \]
- Calculate:
\[ 6 \times 4 = 24 \]
\[ 24 - 9 = 15 \]
- Check if \( 15 = 15 \): **True** (This option is correct)

### Step 3: Evaluate Option 3 (Equals, Minus, Multiply, Minus)
- Substitute the operators:
\[ 6 = 4 \times 9 - 15 \]
- Calculate:
\[ 4 \times 9 = 36 \]
\[ 36 - 15 = 21 \]
- Check if \( 6 = 21 \): **False** (This option is incorrect)

### Step 4: Evaluate Option 4 (Minus, Multiply, Equals)
- Substitute the operators:
\[ 6 - 4 \times 9 = 15 \]
- Calculate:
\[ 4 \times 9 = 36 \]
\[ 6 - 36 = -30 \]
- Check if \( -30 = 15 \): **False** (This option is incorrect)

### Conclusion:
The correct option is **Option 2: Multiply, Minus, Equals, Equals**.
