Q: Lisa makes breakfast for her family every morning, Monday through Friday. She makes 2 eggs for each of her 4 children and 3 eggs for her husband. Then, she makes 2 eggs for herself. How many eggs does Lisa cook for her family for breakfast in a year?
A: Lisa makes 2 eggs / child x 4 children = 8 eggs for her children. She makes 3 eggs for her husband + 2 for herself + 8 for her children = 13 eggs. Lisa makes breakfast 5 days a week for 52 weeks a year, so 5 * 52 = 260 breakfasts. So Lisa makes 13 eggs / breakfast x 260 breakfasts = 3,380 eggs. The answer is 3380.
Question: There are enough provisions in a castle to feed 300 people for 90 days. After 30 days, 100 people leave the castle. How many more days are left until all the food runs out?
Answer: After 30 days, there will be enough food left to sustain 300 people for 90 days – 30 days = 60 days. After the 100 people leave, there will be 300 - 100 = 200 people left. The 200 people will eat 200 / 300 = 2 / 3 as much food as the original group of people in the castle. The 60 days' worth of food will last this smaller group for 60 days / (2 / 3) = 90 more days. The answer is 90.
[Question]If a basket is capable of holding 40 fruit altogether, and there are 3 times as many apples as oranges, how many oranges are there?
[Answer]Since the ratio of apples to oranges is 3:1, that means for every 3 apples there is 1 orange. The size of this group is therefore 3 + 1 = 4. We then divide this group size into the total amount of fruit the basket is holding at this time, which is 40. This means there are 40 / 4 = 10 of these groups in total. Since there are 10 of these groups in total, that means there are 10 * 1 = 10 oranges in the basket. The answer is 10.
