Grandpa Jones says:
“My son Adam is 24 years younger than I and 35 years older than my grandson, Joey. Together our total ages add up to 100.”
Can you figure out the age of each one of them?
Answer
Grandpa Jones was 24 when Adam was born and Joey was born 35 years later, so Grandpa has to be at least 59 years old. Add this to Adam’s age at Joey’s birth to get a total age of 94. If Joey was 1 year old, the total combined ages would be 97 (adding 1 year to every age.) But, if Joey is 2 years old then Grandpa would be 61 and Adam would be 37 and their combined ages would be 100.
