Why do we need to study Quant?

Problem Solving: Businesses have a lot to think about- profits, competitors, regulations, employees and so on. An entrepreneur or a management executive struggles with challenges every minute. You as a future MBA Grad person with quantitative aptitude will be better equipped to handle the problems.

Numbers: Numbers play a crucial role in businesses and commerce in general. Balance sheets, profit and loss calculations, investment analysis, all of these and other such functions require the individual to be comfortable with numbers as he/ she will have to deal with all kinds of numerical data on a day to day basis. Quantitative aptitude, therefore, forms an important pre-requisite for courses such as MBA.

Analysis: An integral part of possessing quantitative aptitude is analysis. Numbers amount to nothing if the proper and correct analysis does not accompany them. A person with a quantitative aptitude will be in a better position to analyse and make sense of the data given.

Accuracy: Quantitative aptitude also ensures one’s accuracy. Given that numbers, percentages, graphs, formulas, analysis are at play, it is crucial for the executive to be highly accurate, as there is little scope for errors.

Most competitive exams and other MBA entrance exams in particular, give a lot of weightage to quantitative aptitude, as the nature of their future jobs demand that they have a certain amount of numerical ability.

Try Attempting these

#Practice Question

Question 2:Ques 1: How many of the integers 1, 2, …, 120, are divisible by none of 2, 5 and 7?

Ques 2: In a class, 60% of the students are girls and the rest are boys. There are 30 more girls than boys. If 68% of the students, including 30 boys, pass an examination, the percentage of the girls who do not pass is?
Ans: 20%
Explanation: Let total number of students in the class = x
Number of girls = 60% of x = 0.6x
Number of boys = x – 0.6x = 0.4x
Given, 0.6x – 0.4x = 30
So, x = 150
Therefore, number of students = 150
Number of boys = 0.4x = 0.4*150= 60
Number of girls = 150 – 60 =90
Number of students who do not pass the exams = 32% of x = 32x/100 = 32*1.5 = 48
Number of boys who failed= 60 -30 = 30
So, number of girls who failed = 48 – 30 = 18
Required percentage = 18/90 *100 = 20%

If you were able to solve these questions, that is really great you can start working on improving your speed through tests & shortcut methods. If you couldn't do these don't worry, follow the video lectures, notes & tests - We are sure you are going to crack the exam!
