One application of linear equations is what are termed age problems. When solving age problems, generally the age of two different people (or objects) both now and in the future (or past) are compared. The objective of these problems is usually to find each subject’s current age.
What is the age after n years?
If the age of a person is ‘x’, then ‘n’ years after today, the age = x + n. Similarly, n years in the past, the age of this would have been x – n years. Answer: Suppose that the present age of the son is = x years. Then the father’s age is (60 -x) years.
How do you calculate age ratio?
It can be calculated by dividing the population 0-14 years and 65 years and older by the population that is in the 15-64 year age group. Example: A community has 41,650 children under age 14 and 6,800 persons age 65 and over.
How do you solve word problems?

- Read through the problem and set up a word equation — that is, an equation that contains words as well as numbers.
- Plug in numbers in place of words wherever possible to set up a regular math equation.
- Use math to solve the equation.
- Answer the question the problem asks.
What is number problem?
In number problems, you are given some clues about one or more numbers, and you use these clues to build an equation. Number problems don’t usually arise on an everyday basis, but they provide a good introduction to practicing the Problem-Solving Strategy.

How do you solve age problems?
If the age problem involves the ages of two or more people then using a table would be a good idea. A table will help you to organize the information and to write the equations. This is shown in the examples involving more than one person.
How do you solve age word problems?
Here’s a run down on what you need to do for a typical age word problem, with a little example. Read the problem carefully. Get rid of clutter. Identify key variables (unknowns). Eliminate unneeded variables. Use the text of the problem to write equations. Solve the equation. Find the remaining variables.
What problems do old people face?
Findings reveal that majority of the elderly, both male and female, are unhealthy. The most common health problems aged people face include eye sight, hearing, joint pains, nervous disorders, weakness, heart complaints, asthma, tuberculosis, skin diseases, urinary problems and others.
