Problems on Ages – Concept and Basics
The problem based on ages asked in the numeric aptitude area are brain teasers that, when read at first, appear to be complicated, but are simple to complete step by step.
Questions in this area are typically asked for 2-3 marks, but age-based questions may be asked as part of the data sufficiency or data interpretation. So it is critical that each and every candidate understands the concept.
As the name implies, the questions are word problems based on the people’s ages. They might be asked in equation or direct form.
Tips and Tricks for Solving Problems on Ages
Candidates who are unfamiliar with the concept and prone to skip or incorrectly answer age problems should refer to the guidelines provided below. These strategies may assist you in answering the question using a specific pattern and then determining the answer.
- The most important thing is to read the question carefully and gradually construct the equation that will help you answer it.
- Basic operations such as addition, subtraction, multiplication, and division will assist a candidate in determining the solution, and no complex computations are necessary.
- Arrange the given values by correctly inserting them in an equation and assigning variables to the unknown values.
- Once the equation has been established, solve it to determine the solution.
- The final step is to recheck the result obtained by inserting it into the equation produced to confirm that no errors occurred throughout the calculation.
The ‘issues on ages’ is one such topic that is not only asked in the first or preliminary phase of the test, but may also be posed in the mains phase in a more complex manner.
Important formulas
Given below are a few formulas connected to the problems on ages that may help you answer the questions faster and acquire a better understanding of the concept:
- If you assume that the current age is x, the age after n years will be (x+n) years.
- If you assume that the current age is x, the age before n years is (x-n) years.
- If the age is given in the form of a ratio, for example, p:q, the age will be treated as qx and px.
- Assuming a current age of x, multiplying by n yields (x×n) years
- If you assume the present age is x, then 1/n of the age must be equal to (x/n) years.
