6.
a grandfather is ten times older than his grand daughter. he is also 54 years
older than her. find their present ages.

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. It IS possible for someone to be 5.4, but with age, not a lot of people care to go down to the decimal point. I then checked the other part. 60 IS 54 years more than 6, so 60 is correct.
