    Answer:

    Given,

    Average weight of 4 boys in a rowing team = 52.2 kg

    total weight of boys = (4× 52.2) kg

    = 208.8 kg

    But, a new boy joins a team

    So,

    Average weight of 5 boys= 52kg

    total weight of boys = (52×5) kg

    =260 kg

    Now,

    we have to find the weight of the boy

    = (260 – 208.8) kg

    = 51.2 kg
