Sure, let's break it down:

- First, calculate 10% of 450:

- 10% of 450 = 0.10 × 450 = 45

- Next, solve the expression within the parentheses:

- 8 × 5 = 40

- Subtract the result of the multiplication from the percentage:

- 45 - 40 = 5

- Now, solve for '?' in the equation 5 = ? × 5:

- Divide both sides by 5 to isolate '?', so ? = 1

- Check options:

- Option 1: 832
