**Basic Numeracy or Numerical Literacy Tests**

They are also referred as basic math tests and cover the foundation concepts. The tests are designed to assess a candidate on the concept of addition, subtraction, multiplication, and division of numbers and fractions. It also assesses averages, decimals, and some key geometrical concept.

Almost all of the companies expect each and every desk job person to be numerical literate. These tests are simple, clear and concise, and are to be done within the allocated time frame.

**Numerical Reasoning Tests**

The concept of ‘Numerical reasoning” is broader than basic numerical literacy test and employ an advanced approach to assessment. This category can be classified as;

**a) Word Problems**

The concept of word problems is very sophisticated. The test is not only a numerical reasoning tool but also measures a candidate’s verbal efficiency. The statement of the question provides a verbal problem, with no illustrations. The statement contains all the necessary information, which points towards the solution of the problem, and a question within. The candidate has to figure out the problem and use the appropriate approach to solve the problem.

**b) Number Series**

The number series problems in a test are very common, and they are designed to look complicated, which in truth, they really are not. Number series are either picked from the existing number series already developed (rational number series, complex number series, arithmetic or geometric series, square series, cube series, Fibonacci series or Golden ration etcetera) or a statement is developed by certain governing logic. The candidate has to find a logic and find the upcoming or missing number from the series.

**c) Ratios and Proportion**

The test assesses the candidate’s knowledge of ratio and proportion, and the relationship of quantities in reference to the degree of variation for different data types.

**d) Financial Arithmetic**

The numerical tests also employ financial calculation such as profit, loss, taxation and currency conversions. The tests often use a common approach, and employ unit conversions from one currency to other, using an exchange rate.

**e) Graphs and Charts Interpretation**

Graphs and charts are one of the most sophisticated approach, used by almost all the major organizations to save time and keep an eye on the progress keenly, by employing visual aid. A graph shows data w.r.t. certain variables. Another form of test can use tables, where the candidate has to draw a conclusion from related data.

Now the most important thing, to be kept in mind is that all of these tests may use functions, percentages, decimals, and fractions all along. The development of these tests suggested to focus on a wide range of ideas, so stay prepared to be challenged while taking the numerical aptitude tests.

**Sufficiency numerical aptitude tests**

With the advancement of science and technology, there is a sudden rise of the specifically designed job description. The number of options has changed, and with this variation, came the concept of better choice. To choose between two options requires the assessment of betterment.

Sufficiency tests present the candidate with two statement; both with a set of the specified data pool. It is to be decided,

- What information is required?

- Which option has sufficient data points?

- Which statement can be used on its own?

- Are both options helpful?

- Does one of the two statements have enough information, on its own?

**Advanced Numerical reasoning aptitude tests**

Advanced Numerical reasoning aptitude tests are used for high-level applications of mathematical operations for analysis and data interpretation. These type of tests often do not have a limitation on the question statements and a candidate may have to think “out of the box” to keep up with the format of the test.

Also, these types of tests are often hard to characterize, but what they all seem to have in common is, the degree of accuracy and precision required for the solution of the tests.
