Yanıt Açıklaması:
The weighted average score is calculated by multiplying the weight of an exam and the score taken in that exam. Thus the scores of students are calculated as follows:
Ahmet: (40*0.4)+(80*0.6)=64
Mehmet: (80*0.4)+(60*0.6)=68
Ali: (40*0.4)+(90*0.6)=74
Asya: (70*0.4)+(90*0.6)=82
Suzan: (40*0.4)+(60*0.6)=52
Then the average score of the group is equal to (64+68+74+82+52)/5=68
