Answer

Answer:

  1. More biographies were sold than travel and science books combined.
  2. There were 5 different types of non - fiction books sold.
  3. Less than half of the sales were biography or science books.

Explanation:

Step1: Check first statement

Travel books sold: 7, Science books sold: 8. Combined: $7 + 8=15$. Biographies sold: 14. Since $14<15$, this statement is false.

Step2: Check second statement

Types are Biography, Cooking, Travel, History, Science. So, 5 types. This statement is true.

Step3: Check third statement

Total sales: $14 + 11+7 + 10+8=50$. Biography or science sales: $14 + 8=22$. Since $\frac{22}{50}=0.44<0.5$, this statement is true.

Step4: Check fourth statement

Cooking books sold: 11, History books sold: 10. Since $11\neq10$, this statement is false.
