The age of the younger individual is 3 years, while the age of the older individual is 21 years.
Two distinct individuals' (or things') ages from the present to the past or future are often compared when resolving age-related concerns. The objective of these puzzles is often to ascertain the current age of each subject.
Let the younger person be x years of age.
The answer to the query is:
Age of senior = (4x + 9) years
Their combined ages are 24.
x+4x+9=24
5x=24-9
5x=15
x=15/5
x=3
Younger person's age is equal to x = 3 years.
Age of senior = 4x + 9 = 4(3) + 9 = 21 years
