Answer:

Nearly 83.33%

Explanation:

There are 12 pairs of cranial nerves connected in the brain.

10 of these pairs are related to the site, smell, taste, and sound.

So,

12 - 100%

10 - x%

Write a proportion:


(12)/(10)=(100)/(x)

Cross multiply


12\cdot x=10\cdot 100\\ \\12x=1,000

Divide by 12:


x=(1,000)/(12)=(250)/(3)\approx 83.33\%
