Question: A bookstore that sells used books sells each of its paperback books for a certain price and each of its hardcover books for a certain price. If Joe, Maria, and Paul bought books in this store, how much did Maria pay for 1 paperback book and 1 hardcover book?
(1) Joe bought 2 paperback books and 3 hardcover books for $12.50.
(2) Paul bought 4 paperback books and 6 hardcover books for $25.00.
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.
Explanation:
Let p be the price for each paperback book, and let h be the price for each hardcover book.
(1) Joe's purchase can be expressed as 2p + 3h = $12.50. Without more information, this equation alone cannot determine the cost of 1 paperback and 1 hardcover book; NOT sufficient.
(2) This statement is equivalent to 4p+ 6h = $25.00. If both sides of this equation are divided by 2, it gives exactly the same equation as in (1); NOT sufficient.
Answer: (e)

Question: Many breakfast cereals are fortified with vitamin supplements. Some of these cereals provide 100 percent of the recommended daily requirement of vitamins. Nevertheless, a well-balanced breakfast, including a variety of foods, is a better source of those vitamins than are such fortified breakfast cereals alone.
Which of the following, if true, would most strongly support the position above?
A. In many foods, the natural combination of vitamins with other nutrients makes those vitamins more usable by the body than are vitamins added in vitamin supplements.
B. People who regularly eat cereals fortified with vitamin supplements sometimes neglect to eat the foods in which the vitamins occur naturally.
C. Foods often must be fortified with vitamin supplements because naturally occurring vitamins are removed during processing.
D. Unprocessed cereals are naturally high in several of the vitamins that are usually added to fortified breakfast cereals.
E. Cereals containing vitamin supplements are no harder to digest than similar cereals without added vitamins.
Question: In Asia, where palm trees are non-native, the trees' flowers have traditionally been pollinated by hand, which has kept palm fruit productivity unnaturally low. When weevils known to be efficient pollinators of palm flowers were introduced into Asia in 1980, palm fruit productivity increased-by up to 50 percent in some areas-but then decreased sharply in 1984.
Which of the following statements, if true, would best explain the 1984 decrease in productivity?
A. Prices for palm fruit fell between 1980 and 1984 following the rise in production and a concurrent fall in demand.
B. Imported trees are often more productive than native trees because the imported ones have left behind their pests and diseases in their native lands.
C. Rapid increases in productivity tend to deplete trees of nutrients needed for the development of the fruit-producing female flowers.
D. Weevil population in Asia remained at approximately the same level between 1980 and 1984.
E. Prior to 1980 another species of insect pollinated the Asian palm trees, but not as efficiently as the species of weevil that was introduced in 1980.
Answer: (c)
