Quantitative Aptitude is a crucial section in most competitive exams, especially those related to banking, management exams, and government jobs. It measures an individual’s mathematical abilities, including topics like arithmetic, algebra, geometry, and data interpretation. This article aims to provide a brief understanding of quantitative aptitude, along with examples and book recommendations by Indian authors.

## Understanding Quantitative Aptitude

Quantitative aptitude measures an individual’s ability to analyze numerical data, solve problems, and make decisions using mathematical reasoning. The section generally comprises multiple-choice questions and requires candidates to have a clear understanding of mathematical concepts and principles. Some of the key topics covered in this section include:

**Arithmetic**: It covers topics like percentage, ratio and proportion, time and work, profit and loss, simple and compound interest, time and distance, etc.**Algebra**: It includes topics like equations, inequalities, quadratic equations, progressions, etc.**Geometry**: It covers topics like lines and angles, triangles, circles, polygons, etc.**Data Interpretation**: It involves analyzing and interpreting data from tables, charts, graphs, etc.

Examples:

Let’s take a look at a few examples to understand it better:

- If the cost price of an article is Rs. 100 and its selling price is Rs. 120, what is the profit percentage?

**Solution**: Profit = Selling price – Cost price = Rs. 120 – Rs. 100 = Rs. 20. Profit percentage = (Profit / Cost price) x 100 = (20/100) x 100 = 20%.

- If x = 2, what is the value of x^2 + 3x + 2?

**Solution**: x^2 + 3x + 2 = (2)^2 + 3(2) + 2 = 4 + 6 + 2 = 12.

- In a triangle ABC, if the measure of angle A is 60 degrees, and the length of AB and AC are 5 cm and 10 cm, respectively, what is the length of BC?

**Solution**: Using the Law of Cosines, we can find that the length of BC is √(10^2 + 5^2 – 2*10*5*cos(60)) = 5√3 cm.
