Question: At a birthday party, 30% of the guests are married, 50% are single, and the rest are children. If there are 1000 guests, how many more married people are there than children?
Answer: There are 1000 x 30 / 100 = 300 people who are married. There are 1000 x 50 / 100 = 500 people who are single. So, there are a total of 300 + 500 = 800 that are either married or single. This means, 1000 - 800 = 200 are children. Therefore, there are 300 - 200 = 100 more married people than children. The answer is 100.

Q: Mike began to train to play basketball every day for a tournament. One day he plays a maximum of 2 hours. After a week of training, he increased the maximum time to 3 hours. How many hours did Mike train during the first two weeks?
A: One week is 7 days, so for one week, Mike trained for 7 * 2 = 14 hours. The second week he began to train for 3 hours a day, so he trained for 7 * 3 = 21 hours. That means Mike in total trained for 21 + 14 = 35 hours. The answer is 35.

[Question]Faith's neighborhood, with a total of 20 homes, decided to install solar panels. Each home needed 10 panels capable of providing their power needs. The supplier of the panels brought 50 panels less than the required amount. The neighbors agreed to only install the panels up to where they'd be finished. How many homes had their panels installed?
[Answer]The total number of panels required is 20 * 10 = 200 panels. When 50 failed to be delivered, the total number available for use became 200 - 50 = 150 panels. If each home requires 10 panels, the number of homes that had panels installed is 150 / 10 = 15 homes. The answer is 15.
[Question]Jonas is trying to expand his wardrobe. He has 20 pairs of socks, 5 pairs of shoes, 10 pairs of pants and 10 t-shirts. How many pairs of socks does he need to buy to double the number of individual items in his wardrobe?
[Answer]
First, we must recognize that all pairs of shoes and socks are actually two items each, whereas the pants and the t - shirts are individual items. Therefore there are 20 * 2 = 40 individual socks in 20 pairs of socks. Similarly, there are 5 * 2 = 10 individual shoes in 5 pairs of shoes. Therefore, Jonas has 40 + 10 + 10 + 10 = 70 individual items in his collection. To double this number, we perform 70 * 2 = 140. This means we need 140 - 70 = 70 new items to double the size. Since there are 2 individual socks in each pair, we take 70 / 2 = 35 new pairs of socks. The answer is 35.
