Uncle Fei bought three boxes of fruit with a total weight of 100 kg. The weight difference between the first two boxes was 11 kg, and the total weight of the first two boxes was three times that of the third box. May I ask: How many kilograms does the heaviest box of these three boxes of fruit weigh?
