I think it's useful for starters.
In this section, you have two types of multiple-choice questions: problem solving dand data sufficiency.
This section measures your ability to reason quantitatively, solve quantitative problems, and interpret graphic data. The two types of questions are intermingled throughout the section. To do this section you have to know basic knowledge about.
* arithmetic
* elementary algebra
* commonly known concepts of geometry
Problem-Solving Questions
Problem-Solving questions are designed to test:
* basic mathematical skills
* understanding of elementary mathematical concepts
* the ability to reason quantitatively and solve quantitative problems
Example:
A grocer has 400 pounds of coffee in stock, 20 percent of which is decaffeinated. If the grocer buys another 100 pounds of coffee of which 60 percent is decaffeinated, what percent, by weight, of the grocer's stock of coffee is decaffeinated?
* A. 28%
* B. 30%
* C. 32%
* D. 34%
* E. 40%
The Answer is: A
Data-Sufficiency Questions
Data-Sufficiency questions are designed to measure your ability to:
* analyze a quantitative problem
* recognize which information is relevant
* determine at what point there is sufficient information to solve a problem
Data-Sufficiency questions are accompanied by some initial information and two statements, labeled (1) and (2). You must decide whether the statements given offer enough data to enable you to answer the question. You must choose one of the following answers:
* Statement (1) ALONE is sufficient, but statement (2) is not sufficient
* Statement (2) ALONE is sufficient, but statement (1) is not sufficient
* BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient
* EACH statement ALONE is sufficient
* Statements (1) and (2) TOGETHER are NOT sufficient
For example:
If 2 different representatives are to be selected at random from a group of 10 employees and if p is the probability that both representatives selected will be women, is p > 1/2
(1) More than 1/2 of the 10 employees are women.
(2) The probability that both representatives selected will be men is less than 1/10.
A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
D. EACH statement ALONE is sufficient.
E. Statements (1) and (2) TOGETHER are NOT sufficient.
The Answer is: E
