Average weight of 5 persons = 64 kg
Average weight of 3 girls = 58 kg
Calculations:
Total weight of 5 persons = 5 × 64 = 320 kg
Total weight of 3 girls = 3 × 58 = 174 kg
Total weight of the 2 boys = 320 - 174 = 146 kg
Average weight of the 2 boys = 146 / 2 = 73 kg
∴ The average weight of the two boys is 73 kg.
