Divisibility by 3

Overview:

While applying for college or a job, the student generally focuses on applying for the aptitude test as a part of self-assessment. Some colleges conduct such tests to understand the abilities of the student. Quantitative aptitude is a crucial part of aptitude tests that analyse the problem-solving and technique handling skills of the student. Divisible by 3 is a problem-solving part of this test for which students need to learn more about the division rules. You can search more on which of the following numbers is divisible by 3 online.

Understanding more about Divisibility tests by 3:

Not everyone has the knack to score well in Mathematics. Besides, for some, the knack for understanding the formulas of Mathematics itself is a challenge. But there are some shorthand techniques and tricks that can always make maths problem solving easy. One of them is the numbers divisible by 3. This calculation formula is quite simple and can increase your chances of scoring better in exams. But some rules need to be followed during these techniques.

Divisibility tests by 3 are a part of divisibility tests in which there is a specific division process that is carried out. The primary aim of this formula is to make the process of division less time taking and easy. Students, however, need to learn the basic rules of such techniques to solve the problem without any hassle. Every divisibility with a certain number has a certain rule associated. Suppose divisibility by 13 has the rule wherein only certain numbers can be divided with 13. In the case of 2, 3, or 4, there will not be much of rules that may confuse you. But considering the divisibility numbers with 7 or 13 may need some additional practice. To know more about which of the following numbers is divisible by 3, you first need to know about the divisibility test.

About the Divisibility Test:

Imagine you have purchased a certain number of chocolates and want to give them to your friends. But you don’t know how to divide these chocolates amongst them without actually going through the whole calculation process. That is when you can use the divisibility rule. This process will help you get the exact number of chocolates that you need to give to each one of your friends present with you at that moment. In this process, if the particular number is divisible by another number, it is then possible to divide, and this whole process is a test of divisibility. Talking of the exact divisibility means there should not be any remainder at all after the certain division.

Divisibility Test by Rules

As stated earlier, if there is any number that can be easily divisible by 3 or the sum of it comes to the number that can be divided by 3, it can be considered for further calculation.

If the number is not divisible by 3, you should not be wasting your time on solving it further.

What are Divisibility Rules for 3?

Consider number 99 if it is easily divisible by 3 or its sum of the digit is, it means there the Divisibility Rules for 3 are applicable.

In the case of 308, if you want to check its divisibility by 3, you need to first take the addition of the digits, which will come to a total of 11. Now, 11 is not divisible by 3 and hence, the entire number itself is not divisible. 

But in the same case, if you take a number like 516 the total of the digit is 12, which is multiple answers of 3. This means this number is divisible by 3.

The Role of Divisibility by 3 in Quantitative Aptitude Test:

Before exploring more about the use of numbers divisible by 3, you need to understand the role of the Quantitative aptitude test. This test comes in different aspects like equation solving. It can be time-consuming, and you aim to finish it in fewer time frames. Since most of this test paper consists of mathematical questions, you can use the right trick to speed up the test. Divisibility by 3 can be a great lifesaver for you in such a test as the test comes with a stringent timeline.

The quantitative test has nearly 30% of the problems that are based on the series of the number or the number system. For some calculation process is needed, while for some, you don’t have to go through the whole process.

It is important to practice problems on the Quantitative Aptitude test. But that will not help to pace your speed to finish the test. Rather, your focus should be on using the right technique that can be efficient, accurate, and time-saving. That is when the use of divisibility by 3 can be done. If your base on understanding the divisibility test becomes stronger, then you can solve the rest of the problems much more quickly and easily. But you must also have clarity on which of the following numbers is divisible by 3.
