Infosys Quantitative Aptitude Questions


Infosys Quantitative Aptitude Questions are designed in such a way to evaluate the student's numerical ability and problem-solving skills. 

Also, it improves the thinking capacity of the brain which in turn increases your speed and accuracy. When we analyzed the previous year's papers, we found that a majority of questions were related to profit and loss, number system, ratio proportion, and percentages. 

The syllabus for the Quantitative Aptitude Questions is as follows...

1. Data Interpretation.

2. Time and work.

3. Distance, time and speed.

4. Probability

5. Permutations and combinations.

6. Profit and loss.

7. Percentages.

8. Allegations.

As you can see, you need to prepare for all the mentioned topics. One nice thing from Infosys is that half of the questions are somewhat easy while half of them are a little difficult. So, preparing well in advance will certainly help you crack the exam.

Once you are done with this, you can move on to verbal ability, logical reasoning.
