Hindustan Petroleum Corporation Limited (HPCL) releases vacancies for the posts of Engineers and technicians in Mechanical, Civil, Electrical, Instrumentation and other departments across its branches all over the country every year.

The HPCL Engineering Recruitment exam is a 2 hour long online test. The exam is conducted in two parts namely, General Aptitude and Technical / Professional Knowledge. In General Aptitude, candidates are tested in three areas i.e., English Language, Quantitative Aptitude and Intellectual Potential.

The quantitative Aptitude Section is one of the most important and high-scoring sections of the HPCL Engineering Recruitment exam. Candidates should create an effective strategy to cover the quantitative aptitude syllabus which is incomplete without proper examination and breakdown of topics in the quantitative aptitude syllabus of the exam.

On that note, let’s go through a topic-wise breakdown in terms of difficulty level and significance to study in them that will help better strategise your quantitative aptitude preparation for the upcoming HPCL Engineering Recruitment exam.

## Breakdown of Quantitative Aptitude Topics as per Difficulty Level

We’ll break the Quantitative Aptitude topics into three categories: Easy, Moderate, and Difficult.

### Easy Topics

Let’s take a look at each easy level topic individually:

Simplification – Every year, one or two questions arise from this topic which are based on simplification techniques like as the BODMAS Rule, fractions, surds and indices, square roots, and so on.

Percentage –Every year, a question about this issue is posed. You should also commit a significant amount of attention to this chapter so that you can calculate the percentage of a given number without using a calculator.

Average – Someone asks a question about this every year. This chapter only requires a basic understanding of math and the ability to perform quick calculations.

Ratio and Proportion – Every year, one or two questions on this topic are submitted at the elementary and secondary levels.

Number System –Every year, a question from this topic is posed, using concepts like LCM and HCF, Irrational or Rational Numbers, and so on.

### Moderate Level Topics

Let’s take a look at each of the somewhat challenging topics individually:

Time, Speed and Distance – The questions in this topic take the form of challenging situations that can only be solved using formulas. Questions on Boats, streams, and trains are asked from this chapter.

Profit and Loss – This topic contributes a few of questions every year. The outline of this chapter consists of basic discount and partnership calculations and concepts.

Simple Interest and Compound Interest – This topic yields one or two questions based on the theory of interest every year. Find out how to calculate basic and compound interest.

Mixture & Alligation – The questions in this topic are typically asked in connection with basic proportion and ratio concepts.

Data Interpretation – In Data Interpretation questions, which are provided in the form of bar graphs, pie charts, tables, and other visual representations, the concepts of ratio and proportion, as well as percentages, are used.

### Difficult Level Topics

Let’s look at each one individually:

Algebra – This topic contributes a number of questions based on the ideas of one- or two-variable linear equations. Some of the sub-topics covered in Linear Algebra include sets, De Morgan laws, Venn diagrams, Complex Numbers, Relation and Function, Number Conversion, Arithmetic, Geometric, and Harmonic Progression, Binomial Theorem, Real Numbers, Permutations and Combinations, Unconditional and Conditional Probability, Logarithms, and more.

Geometry – Geometry is an important chapter because it accounts for a large portion of the HPCL Engineering Recruitment exam’s Quantitative Aptitude component. Try to remember all of the theorems and apply them to scenarios involving triangle congruency, circle, chords, and tangent, among other sub-topics.

In Circles, you can be asked complex questions like finding the angle subtended by a chord at the Centre of a Circle or the length.

Mensuration – Half the battle is won when it comes to preparing the Mensuration if the students understand the shapes and their formulas. The formulas for the shapes Square, Rectangle, Circle, Cone, Cylinder, and others should be remembered.

Trigonometry – Memorize all of the Trigonometric Identities and Formulas that will be required to solve the questions. Enough height and distance questions should be practised.
