Overview and Practice of GRE Quantitative Reasoning |

1 Overview

GRE general test includes a math-related section: quantitative reasoning. It evaluates the ability to reason quantitatively and to address problems with quantitative methods, or say necessary mathematical skills.The questions are in two sorts:

**Pure mathematical problems:**answer by math knowledge only**Word problems:**answer by modeling problems mathematically

- All numbers used are real numbers.
- All figures are in a plane unless otherwise indicated.
- Geometric figures are not necessarily drawn to scale.
- Coordinate systems are drawn to scale

2 GRE Quantitative Reasoning

GRE Quantitative Reasoning isn't real math test. It doesn't test all high school math skills; for example, it does not include trigonometry, calculus, or other higher-level mathematics. Instead, it just covers four primary math parts: arithmetic, algebra, geometry, and data analysis.Arithmetic Topics include properties and types of integers, arithmetic operations, exponents and roots, and concepts of estimation, percent, absolute value, the number line, and decimal representation.

Example:

Directions: Enter your answer as an integer or a decimal if there is a single answer box OR as a fraction if there are two separate boxes — one for the numerator and one for the denominator.

The product of the digits of the number is 15 and the sum of the digits is 8. The digits interchange their places when 18 is added to the number.

Algebra Topics include operations with exponents; algebraic expressions; equations and inequalities; linear and quadratic equations and inequalities; and coordinate geometry, including graphs of functions, intercepts and slopes of lines.

Example:

Directions: Enter your answer as an integer or a decimal if there is a single answer box OR as a fraction if there are two separate boxes — one for the numerator and one for the denominator.

The average age of the 5 members of a family is 25 years. The age of the youngest member is 5 years. What was the average age of the members of the family just before the youngest member was born?

years

Geometry Topics include parallel and perpendicular lines, circles, triangles, quadrilaterals, other polygons, three-dimensional figures, area, perimeter, volume, and angle measurement in degrees. (Not need to construct proofs of geometry.)

Example:

Directions: Enter your answer as an integer or a decimal if there is a single answer box OR as a fraction if there are two separate boxes — one for the numerator and one for the denominator.

A circular park has radius 21 m. It has a road of width 7m running around it on the outside. Find the cost of painting the road at rate Rs 20 per square meter.

Rs.

Data Analysis Topics include basic descriptive statistics; interpretation of data in tables and graphs; elementary probability; conditional probability; random variables and probability distributions, including normal distributions; and counting methods, such as combinations and permutations.

Example:

Find the probability of the occurrence of exactly one of A and B when P(AUB) = 0.59 and the probability of the occurrence of both A and B is 0.01.[AUB = A union B]

3 GRE Quantitative Reasoning Question Type

GRE Quantitative Reasoning has four common types of questions. A question may be promoted in two ways: either independently as a discrete question or as part of a set of questions, the latter case is usually in Data Interpretation whose all questions are based on the same data source, like tables or graphs.Quantitative Comparison is the primary type in GRE quantitative reasoning and usually ask you select one answer choice from multiple options.

Exercises of quantitative comparisonExample:

Directions: Compare Quantity A and Quantity B, using additional information centered above the two quantities if such information is given, and select one of the following four answer choices:

Quantity A is greater.

Quantity B is greater.

The two quantities are equal.

The relationship cannot be determined from the information given.

A symbol that appears more than once in a question has the same meaning throughout the question.

Quantity A is greater.

Quantity B is greater.

The two quantities are equal.

The relationship cannot be determined from the information given.

A symbol that appears more than once in a question has the same meaning throughout the question.

A jar of 90 marbles contains marbles of three different solid colors: red, blue and green. More than half the marbles are either red or blue. | |

Quantity A | Quantity B |

The number of blue marbles in the jar | Twice the number of green marbles in the jar |

Quantity A is greater. | |

Quantity B is greater. | |

The two quantities are equal. | |

The relationship cannot be determined without further information. |

Numeric Entry needs you calculate the answer; some Words Problem question also needs you give the numeric answer after modeling.

Exercises of numeric entryExample:

Sam travels from A to B at 10km/hr and returns at 15km/hr. Pam travels from A to B and returns at 15 km/hr.Pam takes 4 hours less than Sam does. What is the distance between A and B in kilometers?

km

Word Problem emphasizes to translate the problem to the mathematical model, you need to calculate the answer, select one or more choices from multiple options.

Exercises of word problemExample:

Directions: Select answer choice or choices.

If a^{2} = 12, then a^{4} =

72 | |

36 | |

24 | |

16 |

Data Interpretation usually has a set of questions based on the same data source; the problems are diversity, like calculating the answer, selecting one or more choices from multiple options.

Exercises of data interpretationExample:

Directions: The following question 1-2 are based on the bellow table, which shows per capita Mean Expenditure, Per capita Food expenditure, Number of Households and Per capita cereal consumption, in both quantity and value, for different expenditure classes of rural India. The sampled 41597 households are divided into 12 expenditure classes, starting from less than Rs.65 per month per capita and ending at more than Rs.385 per capita per month.

1. According to the results of this sample survey, what is the proportion of total expenditure on food to total expenditure for all the sampled households taken together?

58% | |

36.7% | |

63.3% | |

71% | |

Cannot be determined |

2. What is the difference, approximately, between the gross expenditure of the sampled households in the Rs.95-110 expenditure class and in the Rs.180-215 expenditure class?

372000 | |

448000 | |

496000 | |

93.8 | |

52.3 |
