For every question, four probable answers as (A), (B), (C) and (D) are given. Only one out of these is correct. Choose the correct answer.
If `15 - 15 - 15 xx 6 = x`, then x is :

Options

A. 6
B. 0
C. -90
D. 84

Answer

To solve the equation \( 15 - 15 - 15 \times 6 = x \), we will follow the order of operations known as BODMAS/BIDMAS (Brackets, Orders, Division and Multiplication, Addition and Subtraction).

### Step-by-Step Solution:

1. **Identify the operations**: The equation involves subtraction and multiplication. According to BODMAS, we need to perform multiplication before subtraction.

2. **Perform the multiplication**:
\[ 15 \times 6 = 90 \]
Now, substitute this back into the equation:
\[ 15 - 15 - 90 = x \]

3. **Perform the first subtraction**:
\[ 15 - 15 = 0 \]
Now, substitute this back into the equation:
\[ 0 - 90 = x \]

4. **Perform the final subtraction**:
\[ 0 - 90 = -90 \]
Therefore, we find that:
\[ x = -90 \]

### Final Answer:
The value of \( x \) is \( -90 \).
