Quantitative Section

The quantitative section basically covers :

  • Algebra, Geometry, Number properties, proportions and properties of sets.
  • The level of mathematics is not more advanced then high school mathematics but it involves extra reasoning skills and knowledge.
  • Time Management is very imperative. Easier questions should be allotted less than two minutes and difficult ones should be then given more time, accordingly.
  • Out of 37, about 22 questions will be of Problem Solving and 15 of Data Sufficiency.
  1. Problem Solving
    • If the question asks for a numerical value, the answer choices will increase in size as you read down the list. So if you estimate roughly the size of number, the question asks for, and then you can easily zero in on the most viable answer choices.
    • All the short cut formulas related to arithmetic, algebra etc., should be on tips.
    • Practice the questions keeping a time format in mind while preparing for Problem solving so that you can complete your exam at time.

    Example of Conventional Problem solving Format Question-

    A motorcycle stunts man belonging to a fair ride over the vertical walls of a circular well at an average speed of 54 kph for 5 minutes. If the radius of the well is 5 meters then the distance traveled is:
    • 2.5 kms
    • 3.5 kms
    • 4.5 kms
    • 5.5 kms
    • None of the above
    • Ans. C

  2. Data Sufficiency:
    • The examinee basically has to decide whether or not he/she has enough information in hand to answer a given question.
    • The examinee must be thorough with all the alternatives of data sufficiency so that he may decide quickly for the choice of the related alternative.
    • Be careful not to carry over any information from one numbered statement to another. (Making this mistake is remarkably easy, especially under time pressure and in a momentary lapse of concentration.)
    • If a question asks for a numerical value (as opposed to a quantitative expression that includes variables), the question is answerable only if a numbered statement (1 or 2) yields one and only one possible numerical answer--not a range of values.
    • In distinct contrast to Problem Solving geometry figures, Data Sufficiency figures are not necessarily drawn proportionately--unless a figure indicates explicitly that it is drawn to scale. Do not rely on your eye to measure angle sizes, line segment length, or areas.

Example of Data sufficiency question-

Is the product of x and y greater than 60?

  1. The sum of x and y is greater than 60.
  2. Each of the variables is greater than 2.
  3. Ans: Statement 1 by itself is not sufficient. One of the two variables could be a small fraction. (Think of 500 and 0.01.) Statement 2 by itself could yield the product of 3 and 4. However, the information from both statements is taken together; we can definitively state that the answer to this question is "true."
