If '+' means "minus", "x" means, "divided by "and "-" means "multiplied by", then
`800 xx 10-5+ 86+57= ? `
यदि "+" का अर्थ "घटाना'' है, "x'' का अर्थ "भाग" है, '' +'' का अर्थ "जोड़" है और "-" का अर्थ "गुणा" है, तो `300 xx 10 - 5 + 36+ 57 =` ?

Options

A. 150
B. 171
C. 230
D. 257

Explanation

To solve the expression `800 xx 10 - 5 + 86 + 57` with the given meanings for the operations, we first need to replace the symbols based on the definitions provided:

- `+` means "minus"
- `xx` means "divided by"
- `-` means "multiplied by"

Thus, we can rewrite the expression as:

`800 ÷ 10 × 5 - 86 - 57`

Now, we will solve this step by step:

### Step 1: Division
First, we perform the division:

\[ 800 ÷ 10 = 80 \]

### Step 2: Multiplication
Next, we multiply the result by 5:

\[ 80 × 5 = 400 \]

### Step 3: Subtraction
Now, we will subtract 86 from 400:

\[ 400 - 86 = 314 \]

### Step 4: Final Subtraction
Finally, we subtract 57 from 314:

\[ 314 - 57 = 257 \]

Thus, the final answer is:

\[ \text{The result is } 257 \]
