Question: Out of the 300 comic books in a comic store, 30% are liked by females, males like 120, and both genders don't like the rest. What percentage of the comic books are disliked by both males and females?
Answer with step-by-step thinking: The number of comic books that females like is 30 / 100 * 300 = 90 books. Together, both males and females like 90 + 120 = 210 comic books. The number of comic books that are disliked by both males and females is 300 - 210 = 90. The percentage of books that are disliked by both genders is 90 / 300 * 100 = 30%.
So the answer is 30.


Question: There are four members in one household. Each member consumes 3 slices of bread during breakfast and 2 slices of bread for snacks. A loaf of bread has 12 slices. How many days will five loaves of bread last in this family?
Answer with step-by-step thinking: A total of 3 + 2 = 5 slices of bread are consumed by each member every day. So a family consumes a total of 5 x 4 = 20 slices of bread every day. Five loaves of bread have 5 x 12 = 60 slices of bread. Thus, the 5 loaves of bread last for 60 / 20 = 3 days.
So the answer is 3.


Question: Jack went to a supermarket with $100 and bought 4 bottles of water. Then his mother called him and asked him to buy twice as many bottles as he already bought. Each bottle cost $2. Finally, he also bought half a pound of cheese and 1 pound of cheese costs $10. How much money does Jack have remaining?
Answer with step-by-step thinking:
Jack's mother asked him to buy 2 * 4 = 8 bottles of water. Thus Jack bought 4 + 8 = 12 bottles of water in total. Altogether, the bottles of water cost 12 * $2 = $24. The cheese cost 1 / 2 * $10 = $5. So Jack spent $24 + $5 = $29 on water and cheese. Since he started with $100, he now has $100 - $29 = $71 left.
So the answer is 71.
