Explanation:

Let’s break it down:

- The equation is:

3 × ? ÷ 9 = ?729 × v121

- First, note the typo: "?729" probably means "729" (since ? is used for the missing number elsewhere).

- v121 is just 11.

- So:

3 × ? ÷ 9 = 729 × 11

3 × ? ÷ 9 = 8019

- Multiply both sides by 9:

3 × ? = 8019 × 9

3 × ? = 72171

- Now divide both sides by 3:

? = 72171 ÷ 3

? = 24,057

- Now, look at your options:

1. 197

2. 300

3. 297

4. 295

5. None of these

- None of the options match 24,057.

Here’s what this means:

- All calculations point to a number that’s not on the list.

- So, the right answer is Option 5: None of these.

To sum up:

- None of the listed numbers work.

- Option 5 is the only one that fits after checking the math.
