Question

Jason is a body builder. Despite being more fit, he weighs more than his brother Ryan, who is the same height. Which is a possible reason?

Answer 1

So, if they have the same height, this means that the difference in weight could be due to being overweight- but we know that Jason is a body builder, so this is not the case.

The answer is that Jason's muscles weigh more than Ryan's' -and that's why Jason is heavier.
