Look at the calendar below.
Let us mark 3 × 3 boxes (9 dates) on the calendar and see some magic.
| Take the smallest number | 3 |
| Add 8 to it | +8 |
| = | 11 |
| Multiply it by 9 | ×9 |
| Total | 99 |
Now you choose any 3 × 3 boxes from a calendar and find the total in the same way.

उत्तर
Take the smallest number = 4
Add 8 to it, 4 + 8 = 12
Multiplying it by 9, 12 × 9 = 108
So, the sum of all the numbers in the selected box is 108.
