- The average weight increase is 2 kg for 25 boxes, so the total weight increase is 25 x 2 = 50 kg.

- The new total weight is the old total weight + 50 kg.

- The old total weight is 25 boxes x old average weight.

- One box weighing 68 kg is replaced.

- Assuming there is an old average weight of \(X\), the equation is \(25X + 50 = 25(X + 2)\).

- The new box's weight is the old weight minus the replaced box weight plus the 50 kg.

- Replacing results in \(25X + 50 - 68 + \text{new box} = 25(X + 2)\).

- The new box weight calculation: 68 + 50 = 118 kg.

- Option 2: 118 is the correct answer.
