Q2. In a certain class a professor awards his students grades A, B, C, D,
and F. If at least one of the grades has 6 or more students, what is
the least total number of students in the class?
(A)30 (B)27 (C)26 (D)25 (E)22
Ans.(C)
這題我的想法是,只要有一個grade有6個學生那其他grade低於6,
這樣(E)不是更好?
想了很久還是想不通,希望有人能夠幫忙解答,謝謝^^
