Given:

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.
