    Vamos ver se eu entendi
    A mdia de 50 nmeros 38, ento vamos desfazer essa mdia, ok?

    Y= 38×50
    Y= 1900

    Se dois nmeros foram tirados, e estes, 55 e 21, vamos tir-los de 1900.

    1900 — 55 — 21 = 1824

    E agora fazer a mdia novamente, lembrando que se tiramos dois nmeros, vamos dividir por 48 e no 50!

    1824/48 = 38!
    A mdia dos que restaram 38. Tem algum gabarito para conferir a resposta? rs Espero que tenho ajudado, boa noite. 😀
