­so in this ques part 1 - weighted average I used a technique but I am not sure if the approach is correct, can someone please confirm 

I considered the scoring of Hernandis coz his scores were integers
so I 
(72a+74b+75c)/ a+b+c=74 where Abc were asigned weights to Exam1,exam2 and final respectively 
74B got cancelled on both sides giving me c=2a 

then i took Nguyens score
(70a+74b+72c)/a+b+C=72
now 72c got cancelled giving me A=B 

so i made a ratio of A:B:C= 1:1:2 

Giving my final as a "no" 

Is this approach correct?­
