The number of bones in the hands and feet of an adult human, compared to the total number of bones in a human, is approximately what percentage?

Correct answer: (d) 50%

Explanation

An adult has 206 bones. Each hand (with the wrist) has 27 bones and each foot (with the ankle) has 26, so the hands and feet together have 106 bones.

That is just over half the skeleton, about 50%.
