C) Guess
A lot of precise and concise elements are enlisted in this description which does not leave any space for expectations

Answer: Grandpa: 60 Granddaughter: 6
Explanation: When I first saw this, I noticed you can not get one solid whole number with a number like 54, so I rounded it up to 60, because 10 percent of 60 is 6.
