2． A school wants to recruit a mathematics teacher. The school conducted three ability tests on three candidates A, B, and C. The full score of each test was 100 points.

(1) It can be seen from the table that A’s average score is (85 70 64)/3=73,

B’s average score is (73 71 72)/3=72 ,

C’s average score is (73 65 84)/3=74,

Because 72<73<74, C’s average score is the highest, so C will be admitted.

(2) A’s score is 85×5/10 70×3/10 64×2/10=76.3

B’s score is 73×5/10 71×3 /10 72×2/10=72.2

C’s fraction is 73*×0.5 65*×0.3 84*×0.2=72.8

Because 72.2 < 72.8 < 76.3 A’s fraction The highest, so A will be admitted
