[Question]A company is hosting a seminar. So far, 30 attendees from company A have been registered; company B has twice the number of attendees of company A; company C has 10 more attendees than company A; company D has 5 fewer attendees than company C. If a total of 185 attendees have registered, how many attendees who registered are not from either company A, B, C or D?
[Answer]There are 30 x 2 = 60 attendees from company B. Company C has 30 + 10 = 40 attendees. Company D has 40 - 5 = 35 registered attendees. So, the total attendees from company A, B, C, and D is 30 + 60 + 40 + 35 = 165. Therefore there are 185 - 165 = 20 attendees that are not from companies A, B, C, or D. The answer is 20.
Q: Levi and his brother were playing basketball. Levi had scored 8 times and his brother had scored 12 times. Levi was determined to beat his brother by at least 5 baskets. How many more times does Levi have to score in order to reach his goal if his brother scores another 3 times?
A: Altogether, Levi's brother scores 12 + 3 = 15 times. If Levi wants to beat him by 5, he needs to score a total of 15 + 5 = 20 times. Levi needs to score another 20 - 8 = 12 times. The answer is 12.
Question: Dimitri eats 3 burgers per day. Each burger has a total of 20 calories. How many calories will he get after two days?
Answer: The total number of calories he gets per day is 20 x 3 = 60. Therefore the total number of calories he will get after 2 days is 60 x 2 = 120. The answer is 120.
[Question]A dragon hoards jewels and gold in its cave. A jealous king snuck in and stole three prize jewels. The dragon burned him to a crisp and stole back its jewels, along with twice as many of the king's crown jewels from his crown that melted in the dragon's fire. The new jewels were a third of the number of jewels the dragon had owned before. How many jewels did the dragon own in the end?
[Answer]The dragon stole 2 * 3 = 6 of the king's crown jewels. The dragon owned 6 * 3 = 18 jewels before the theft. Thus, the dragon owned 18 + 6 = 24 jewels in the end. The answer is 24.
Q: Hugo can fold a small box in 3 seconds and a medium one in twice that time. Tom can fold both the small and medium boxes in 4 seconds. If Hugo and Tom want to leave as early as possible, how long (in seconds) will it take them to fold 2400 small boxes and 1800 medium boxes?
A: If it takes Hugo twice the amount of time to fold a medium box than a small box, then he needs 2 * 3 = 6 seconds for the medium box. If Tom can fold either the small or medium box in 4 seconds, then he's faster at folding the medium box than Hugo because 4s < 6s. If Hugo can fold the small box in 3 seconds, then he's faster at folding the small boxes than Tom because 3s < 4s. Therefore Hugo should fold all small boxes and Tom should fold all the medium ones before doing the other size where they are slower. If there are 2400 small boxes and Hugo can fold 1 box in 3 seconds, then it would take him 2400 * 3 = 7200 seconds to fold all boxes. If there are 1800 medium boxes and Tom can fold 1 box in 4 seconds, then it would take him 1800 * 4 = 7200 seconds to fold all medium boxes. Given that they need the same amount of time to fold all boxes, and are doing it simultaneously they will need 7200 seconds to fold all the boxes. The answer is 7200.
Question: Anna puts three slices of ham in each sandwich. If she has 31 slices of ham, how many more slices of ham does she need to make 50 ham sandwiches?
