There is a bookstore with one hundred picture books. Monday saw the sale of 25% of the books, followed by Tuesday's sales of 31% and Wednesday's sales of 7%. Five books are returned on Thursday. How many picture books is the bookstore still carrying?

Answer: 42

The right response is 42. This problem requires several stages to solve. Let's examine each day in detail. On Monday, there are one hundred books. 25 out of 100 are sold, meaning that 25% of them are sold. To calculate the remaining number of books, we now deduct 25 from 100: 100 - 25 = 75. Tuesday: There are 75 books to begin with. Now that 31 of them have been sold, we deduct 31 from 75 to determine the remaining number of books: 75 – 31 = 44. Wednesday: Let's begin with 44 immediately. After 7 of them are sold, we deduct 7 from 44 to determine the remaining number: 44 – 7 = 37. Thursday: There are 37 books to begin with. Since five books were returned, the number of volumes remaining is now 42 (37 + 5). Thus, 42 books is the right response.

Decrease → Increase : Shallow →

Answer: Deep

The right response is complex. Decrease and increase, the first pair of words, are opposites. To make something smaller, use the term decline, and to make something larger, use the word increase. The second set of words has to adhere to the same structure. Because the first term is shallow, the next word must represent the opposite, making profound the right response.
