Answer 1

Actually, fat does not weight that much in comparison with muscle, in this case, the reason that Jason weighs more than his brother is they possess the same height is probably because Jason has a different body mass index or in other words he has more muscles on relation to his mass.

Answer 2

the most possible explanation would be : A. Jason has more muscle mass than ryan does
Being more fit doesn't always mean that you have less weight. The more muscle mass a person has, the more power he'd be able to generate during his/her activity

hope this helps
