Age word problems

Age problems are algebra word problems that deal with the ages of people currently, in the past or in the future.

If the problem involves a single person, then it is similar to an Integer Problem. Read the problem carefully to determine the relationship between the numbers. This is shown in the example involving a single person.

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 algebra help is shown in the age problems: examples involving more than one person.

Question:-

j was twice as old as his brother four years ago.j was 4 times as old as his brother ,what is the current age of j?

Answer:-

Let the brothers age be x

So j=2x ------> Now--1

four years ago

 j-2x=4(x-4)----->2

 j=4(x-4)+4

  =4x-12-------3

use equation 3 in 1

j=2x

4x-12=2x

2x = 12

x=6

So j=2x
 =2*6

 j=12 years
