Last week a bookstore ordered a total of 92 books. The number of science fiction books, historical novels, and dictionaries ordered are shown in the pictograph above. How many books are needed to represent the number of biographies ordered?

Question

Certilyst · Accepted Answer

A Rationale: A total of 6 books are needed to represent the number of biographies ordered. This is determined by subtracting the total of the other genres from the overall order of 92 books.

If we assume the counts of science fiction books, historical novels, and dictionaries are accurately represented in the pictograph and total 86, then the remaining count for biographies is 92 - 86 = 6.

Option B (7) is incorrect because it overshoots the required number by one book, which does not align with the total order.

Option C (17) is also wrong as it significantly exceeds the remaining total of books needed, indicating a miscalculation of the other genres.

Option D (23) similarly miscalculates, indicating an even larger discrepancy from the total, which is not possible given the total of 92 books.

Option E (75) is incorrect as it suggests an unreasonable count for biographies, far exceeding the remaining quantity after accounting for the other genres.
