Every state takes competitive examinations to shortlist new talent. Millions of students appear in these kinds of examinations each year. Every exam has its own parameters to be fulfilled, appear, pass, and qualify. But age is one of the most important factors that is kept under strict observation while selecting candidates for the role.
And this is why you should know what is your age exactly. You can also do it with the age calculator, and advanced online resource that quickly tells you how old are you. With that, you may know some related insights about your age that might also increase your knowledge.
In the following blog below, we have compiled some age queries that students might find tricky to solve. But in reality, it is super simple to find their solution. Let us know how!!!
Queries on Age – Basics You Should Know
Before moving to the questions, let it be clear that you should be mentally tight enough to tackle numbers, ages, and descriptions of ages. Age questions can be asked in different ways. They can be either in the form of equations or descriptive-type questions.
Adding more, age questions never exceed 3 or 4 in examinations. These kinds of questions are asked to check your mental capabilities. So let us learn how to solve these!
How to Solve Problems on Ages?
While preparing for examinations, you can get assistance from the age calculator. The tool will help you understand how you could determine age manually as well. It shows you a clear difference between your date of birth and your current date. You can count days between dates and solve the problem in minutes.
Main Concept:
Suppose there is a person with age X, then we have;
- After n years his age = X+n
- And after n years ago, his age = X-n
- If we multiply n with X, we get = nX
Now if you mention the ages in the respective ratios of A:B, then we have:
A:B = A:X and B:X
If ages in the numerical are mentioned in the ratio A:B, then A:B will be AX and BX
The following formula can be used to find the age of Y if the total of their ages is X and Y and their respective ratio is p:q:
Age of Y = Ratio of Y/ Sum of ratios x sum of ages
Age of Y = q/ (p+q) x A
Key Formulas To Remember:
- Assuming x to be the current age, (x+n) years will be the age after n years
- Assuming x to be the present age, the age prior to n years will be (x-n) years
- In case the age is expressed as a ratio, as p:q, it will be interpreted as qx and px
- Assuming that the age at this moment is x, you will get (x×n) years if you multiply the present age by n
- Assuming that the age is x at this point, 1/n of the age equals (x/n) years
All of these formulas will certainly let you master the age-related questionaries in the competitive examinations.
Sample Example:
If Reshaeel’s age after 15 years will be 7 times of his age 5 years ago, how old is Reshaeel now?
If the question was about age calculation, then the age calculator could done it in less than a second. But now, you have to dig more into the concept.
Solution:
Make a supposition that Reshaeel is X years old
Reshaeel’s age 5 years ago = X-5
Reshaeel’s age after 15 years = X+15
(x +15) = 7 (x-5)
x+15=7x-35
x-7x=-35-15
-6x=-50
x=50/6
x=8.3 years
To check how old Reshaeel will be in months, weeks, days, hours, minutes, and seconds, you can simply enter his DOB and the current date as a date after 8.3 years. You will get your answer in moments.
Additional Tips:
- The most crucial step is to carefully consider the question and progressively create the equation that will enable you to provide a response
- A candidate will find that solving problems involving addition, subtraction, multiplication, and division requires no complicated math and can help them arrive at a solution
- Assign variables to the unknown values in order to precisely arrange the given values in an equation
- After the equation is finished, solve it to find the solution
- To ensure that no calculations went wrong, the last step is to double-check the answer by entering it into the equation
