Question: An investment bank gives 10 percent interest at the end of every month. How much money in total will you have, including interest, at the end of 2 months if you invest $300?
Answer: Step-by-step reasoning process: After the first month you get 10 / 100 * $300 = $30 interest. After the first month you will have $300 + $30 = $330 in total. After the second month you get = 10 / 100 * $330 = $33 interest. After the second month you will have $330 + $33 = $363 in total.
So the answer is 363.

Question: The total number of lions in a park is twice the number of leopards in the same park. The number of elephants is half the combined number of lions and leopards. Calculate the total population of the three animals in the park if the number of lions is 200.
Answer: Step-by-step reasoning process: If there are 200 lions in the park, which is twice the number of leopards in the park, there are 200 / 2 = 100 leopards in the park. The total population of lions and leopards in the park is 200 lions + 100 leopards = 300. The number of elephants in the park is 1 / 2 the total population of lions and leopards; thus, there are 300 / 2 = 150 elephants in the park. There are a total of 150 + 300 = 450 animals in the park.
So the answer is 450.
