#### The average weight of 16 boys in a class is 50.25 kg and that of the remaining 8 boys is 45.15 kg. Find the average weights of all the boys in the class.

$\\\text{Average of 16 boys} = 50.25 \\ \text{Therefore, sum of weight of 16 boys}= 50.25 \times 16 = 804 kgs \\ \text{similarly weight of remaining 8 boys} = 45.15 \times 8 =361.2 kgs \\ \text{Therefore total weight} = 804 + 361.2 = 1165.2 kgs \\ \text{Then, average weight of total students} = \frac{1165.2}{24} =48.55 kgs$
