Explanation:

- Start by calculating the sum and subtraction of given numbers:

- 91.97 + 26.98 = 118.95

- 118.95 - 83.90 = 35.05

- Add this result to 112.98:

- 35.05 + 112.98 = 148.03

- Add 10² (which is 100) to this result:

- 148.03 + 100 = 248.03

- The calculations indicate that the approximate value for '?' is 248.

- Match the result with the given options:

- Option 1: 279

- Option 2: 360

- Option 3: 150

- Option 4: 248

- Option 5: 149
