LESSON 12 Solving Age Problems
When you encounter an age problem, you will often see that the problem
gives you information about the age of a person in the future or in the past.
For example, if a mother is three times as old as her daughter, their present
ages can be represented as
Letx¼the daughter’s age and
3 x¼the mother’s ageNow if the problem gives you information about their ages, say, 6 years
from now, you can represent their future ages as
Letxþ 6 ¼the daughter’s future age and
3 xþ 6 ¼the mother’s future age121
