Answer:
Max
Step-by-step explanation:
Max percentage improvement in the first exam = [tex](\frac{6}{20}[/tex] ×[tex]100)[/tex] %
=[tex]\frac{600}{20}[/tex]%
= [tex]30[/tex]%
Maria percentage improvement in the first exam =[tex](\frac{30}{90}[/tex] ×[tex]100)[/tex]%
= [tex]\frac{3000}{90}[/tex]
= [tex]33.3333333333[/tex] Round [tex]33.33[/tex]%
Hence, 30% < 33.33%
Therefore, Max showed less improvement.
