Problem on Ages

Age is defined as a period of time that a person has lived or a thing has existed. Age is measured in months, years, decades and so on.
Problem based on age generally consists of information of ages of two or more persons and a relation between their ages in present/future/past.
Using the information, it is asked to calculate the ages of one or more persons in present/future/past.
Important Formulas on "Problems on Ages" :
1. If the current age is x, then n times the age is nx.
2. If the current age is x, then age n years later/hence = x + n.
3. If the current age is x, then age n years ago = x - n.
4. The ages in a ratio a : b will be ax and bx.
5. If the current age is x, then 1 of the age is x .

MIND IT !
Mostly questions on ages can be solved with the use of linear equations. So, the method to solve linear equations is important for this chapter which are discussed in chapter equations.
