  1. Sir, solve this question for me
    i m very interested with it
    i found it on website



    solve it out as soon as possible!! thx!!

  2. 老师 这题怎么解释丫?

    三個人去投宿 , 服務生說要300元
    於是叫服務生把退的50 元拿去還給他們
    服務生想自己暗藏20元起來,於是就把 剩下的30元還給他們
    那三個人每人拿回10元100-10=90 表示每個人只出了90元投宿
    90X3+服務生的 20元=290 那剩下的10元呢??
