The GRE Quantitative Reasoning section contains 20 questions to be answered within 35 minutes, i.e., less than two minutes per question. A good grade in the GRE Quantitative Reasoning section is 160 or higher. To achieve this score, you must correctly evaluate 15 to 16 questions in each of the two sections for quantitative reasoning and quantitative comparison.
In such a scenario – quantitative comparison (QC) questions may be even more important – you can expect 6 to 8 questions of this type in each part of quantitative thinking. If you do it right, you can always solve it in a minute, saving you time for many time-consuming issues, such as interpreting data.
As we all know GRE is not easy as it seems. Sometimes solving the quantitative comparison can be time-consuming. As in result, you may not be able to attempt all the questions in your GRE exam. So it is wise to use the take my online gre exam help to get the best of the exam.
What is this strange-sounding question about quantitative comparison? You get two numbers of data, and your job is to identify the relationship between the two numbers.
Quantitative Comparison Questions Characteristics
Each question for quantitative comparison has the following characteristics:
- Two numbers can be described in sentences or algebraic expressions, or even geometric numbers.
- Find out more about the situation or context. It is optional and can be lost on many issues.
- Four options are the same for all questions.
a. The Quantity A is greater than the Quantity B
b. Quantity B is greater than quantity A.
C. The Quantity A equals the Quantity B.
You can not determine a relationship from the available information.
You do not have to deal with these issues, and perhaps you will know which of these numbers is greater. The four options for these questions are also always the same – there is no need to reread them during the exam. In addition, the questions are about identifying the correct answer rather than using large formulas or calculations.
To give a simplified example, which of the following is larger? 64 x 342 or 23x 66? It is straightforward to notice that the first expression is larger than the second one, although none is simplified. That’s what the test expects of us.
Comparing the two numbers seems easy – but as we all know, GRE is a tricky and cumbersome test, and questions about quantitative comparison are the perfect pitfalls that tempt you to point out a wrong opportunity. What seems simple is usually not, and you can consider many cases before deciding on a relationship between two evening numbers.
The values can be a specific amount – 85% of 650, where you can use a calculator to get an answer. Another variant is that the number is given as a sign – the number of prime numbers without 100 and finally, the last variant, where the number becomes an algebraic expression. The third case had a higher level of difficulty than the second case, with a higher level of difficulty than the first.
We usually use three strategies to get these questions answered quickly and accurately while ensuring we don’t fall into the trap.
Common Pitfalls of Quantitative Comparison
Although there are many different issues in this area, we have noticed some recurring topics.
Many students use intuition to get answers. Consider a question that compares n2 and n3. Intuition tells us that n3 is larger. We must remember that these two numbers are equal if n is 0 or 1. Although 0 <n <1, n2> n3. While intuition can be useful in many areas, it should not be allowed to tempt you with these questions.
Students often try to substitute one or two values and decide on a relationship. It forces them to omit a scenario where the relationship is not always the same. Consider the relationship between x2 + 4x-32 and x2-36. Replacing small integer values indicates a relationship that is not always maintained.
Some questions contain lengthy calculations that are not even necessary to identify the relationship. Here is a sample question: f (x) = x5-11x + 10; g (x) = x5 + 12x-11. Which of the following is the larger f (17)? o g (17)? In such a question, we should note that [17] 5 is part of two figures and has no effect on the comparison. Once we ignore this, the issue will be easier to resolve.
Queries sometimes contain variables whose values are unknown, which often leads students to decide that a relationship cannot be established. However, there are many scenarios where the relationship is not affected by the unknown.
Solving the Quantitative Comparison Equation GRE – Four Magical Methods
Solving the quantitative equation can consume lots of time if you do not use the trick to solve it in less time. You can use the take my online GRE exam for me to get the best result for your upcoming GRE. In general, three compelling methods can address quantitative comparison issues. According to the question, one must choose the most suitable one for answering the question.
Subtraction Method
If the expressions look the same but contain some different expressions, it may be a good idea to subtract them. The proof that A – B is greater than zero is the same as the proof that A> B. We can save a lot of time.
Method of Division
Sometimes we can cancel multiple factors if we divide them by two numbers. If both A and B are positive, the proof that A / B is greater than 1 is the same as the proof A> B. Remember not to cancel an expression that becomes zero. Deleting a negative number can also cause more complexity, which should address carefully.
Substitution and Contradiction
If there is a strong intuition that the relationship is not stable, you can try substituting some amounts to show that the relationship is not stable. This method cannot be used to establish a relationship – just to show that it is not solid.
Approximate Numerical Questions
If the question only concerns numbers without included variables, see if you can estimate the values. Sometimes calculations can be complicated, even with a calculator, and only perform a complete analysis if the numbers appear close.
