Whether you want to attain your dream of higher education or want to secure a high profile job, qualifying competitive exams has now become essential for everything. Along with the English and Logical Reasoning section, the Arithmetic Reasoning (AR) section is also a part of various competitive exams. Arithmetic Reasoning section includes a variety of questions that are based on mathematical concepts, thus, students often find it difficult to solve such questions. If you are preparing for AR, go through this blog which aims to help you understand these concepts better.
What is Arithmetic Reasoning?
When you are acquainted with the concepts of arithmetic reasoning, you will be able to easily solve any question. The AR questions do not involve complex calculation rather the questions tend to play with your mind with the tricky concept and language. You can practice the questions easily by using simple mathematical operations, arithmetic operations etc. Listed below are the main types of questions which are offered under this section-
- Algebra Questions
- Ratio and Proportion Questions
- Percentage Questions
- HCF and LCM Questions
- Ages Questions
- Games and Tournaments
- Sequence and Patterns Questions
Now that you are familiar with the basics of Arithmetic Reasoning, let us go through some solved examples to understand the concept in a better way.
Example 1: Riya is 2 times older than Priya. 3 years ago, the sum of their current ages will be 66. What are their present ages?
Let us begin by assuming their ages
Assume that Riya’s age is x
Its is given that the Priya is twice as old as Riya, then, Priya’s age will be 2x
After 3 years,
Riya’s age= x + 3
Priya’s age= 2x + 3
Their total sum is 66
Hence, the equation becomes,
x+ 3 + 2x + 3= 66
3x + 6 = 66
3x= 66- 6
3x = 60
x= 60/ 3
So, the age current age of Riya is 20 and that of Priya is 40
Example 2: Find the number which when multiplied by 3/4th of itself gives out the value 10800.
Let us begin by assuming that the number is y
Then 3/4th of y would be (y x 3/4)
As per the question,
y x (y x 3/4) = 10800
3/4 y 2= 10800
y 2= 10800 x 4/3
y 2= 14400
y = 14400
y = 120
We hope that after these solved examples, you will be able to solve the below-mentioned Arithmetic Reasoning questions.
