Official Explanation
Statement 1 (False): There are 4 titles by female authors and 26 by male, making the ratio 4: 26 or 2:13. (Note that the fraction of new titles by female authors is 1/6).
Statement 2 (True): The total number of titles in the five periods (adding "male" and "female" numbers) is 15 + 10 + 10 + 5 + 3 = 43 and the average over the five periods is obtained by dividing the total by 5 to give 8.6.
Statement 3 (False): A total of 178 new titles were published in period 1 and 175 in period 5. These numbers are close and so although this question is easy, it is time consuming.
