Common Types of Problems on Ages<\/strong><\/h2>\n\n\n\n

Let\u2019s first understand the common types of questions that appear in the exam.<\/p>\n\n\n\n

1. Present Age-Based<\/strong><\/h3>\n\n\n\n

Here, the question talks about current ages. You simply form equations and solve.<\/p>\n\n\n\n

For example, A is twice B\u2019s age today. Four years from now, their total age will be 50. Find their current ages.<\/p>\n\n\n\n

These are the most common type and the easiest to solve.<\/p>\n\n\n\n

2. Ratio Based<\/strong><\/h3>\n\n\n\n

Sometimes, the ages are given as a ratio. You may also get the ratio for two different time periods.<\/p>\n\n\n\n

For example, A : B = 4 : 5 today. After 6 years, A : B = 5 : 6. Find their present ages.<\/p>\n\n\n\n

Ratios help you find actual ages quickly if you know the total or the difference.<\/p>\n\n\n\n

3. Past Age-Based<\/strong><\/h3>\n\n\n\n

These talk about ages some years ago.<\/p>\n\n\n\n

For example: Five years ago, A was three times B. Find their present ages.<\/p>\n\n\n\n

Here, you need to work backwards to solve such questions.<\/p>\n\n\n\n

4. Future Age-Based<\/strong><\/h3>\n\n\n\n

These give conditions about ages after some years.<\/p>\n\n\n\n

For example, after 8 years, A will be twice B. Find their present ages.<\/p>\n\n\n\n

5. Mixed Type<\/strong><\/h3>\n\n\n\n

These mix present, past, and future data in one question.<\/p>\n\n\n\n

For example: \u201cA\u2019s age five years ago was twice B\u2019s age ten years ago\u2026\u201d<\/strong><\/p>\n\n\n\n

You need to be patient and solve such questions in steps. <\/p>\n\n\n\n

To solve all the questions mentioned above, you need to master some basics and formulas. Let’s discuss them!<\/p>\n\n\n\n

Basics and Important Formulas<\/strong><\/h3>\n\n\n\n

Formulas are the routes that take you to the solution of a problem. Here are some rules you must keep in mind for every question:<\/p>\n\n\n\n

Age Difference is Constant<\/strong><\/h4>\n\n\n\n

The difference in ages never changes. If A is 10 years older than B today (the 10-year gap will always remain there in between them), A will be 10 years older in the future as well as in the past.<\/p>\n\n\n\n

Sum of Ages Rule<\/strong>:<\/h4>\n\n\n\n

If two people\u2019s ages sum to S today, after n years their sum will be S + 2n.<\/p>\n\n\n\n

For three people, add 3n instead.<\/p>\n\n\n\n

Ratio and Sum Formula<\/strong><\/h4>\n\n\n\n

If you know the ratio and the total sum:<\/p>\n\n\n\n

Actual Age = (Ratio Part \u00f7 Total Parts) \u00d7 Total Sum.<\/p>\n\n\n\n

Equation Translation<\/strong><\/h4>\n\n\n\n

Change statements into equations quickly.<\/p>\n\n\n\n

For example: \u201cFour years later, A will be twice B\u201d \u2192 A + 4 = 2(B + 4).<\/p>\n\n\n\n
