46.15

- First, calculate the total weight of the 18 boys: \(18 \times 45 = 810\) kg.

- Then, calculate the total weight of the remaining 8 boys: \(8 \times 48.75 = 390\) kg.

- Add the total weights of both groups: \(810 + 390 = 1200\) kg.

- There are a total of 26 boys in the class.

- The average weight of all the boys is \(\frac{1200}{26} \approx 46.15\) kg.

- Therefore, Option 3: 46.15 is the correct answer.

- The answer should be precise to two decimal places.
