Question: In four years, Peter will be twice as old as Harriet. If Peter's age is currently half of his mother's age, who is 60, how old is Harriet now?
Answer: If Peter's age is currently half of his mother's age, who is 60, Peter is 1 / 2 * 60 = 30 years old. In four years, Peter will be 30 + 4 = 34 years old. Since Peter's age in four years will be twice Harriet's age, Harriet will be 34 / 2 = 17 years old in four years. Currently, Harriet is 17 - 4 = 13 years old. The answer is 13.

Question: Dante needs half as many cups of flour to bake his chocolate cake as he needs eggs. If he uses 60 eggs in his recipe, calculate the total number of cups of flour and eggs that he uses altogether.
Answer: Dante needs half as many cups of flour to bake his chocolate cake as he needs eggs, meaning he needs 60 / 2 = 30 cups of flour for his recipe. Altogether, Dante needs 30 + 60 = 90 eggs and cups of flour for his recipe. The answer is 90.

Question: Five percent of the 300 senior students got a full merit college scholarship and ten percent of them got a half merit scholarship. How many senior students did not get any scholarships?
Answer: 300 x 5 / 100 = 15 senior students got a full merit scholarship. 300 x 10 / 100 = 30 senior students got a half merit scholarship. So, a total of 15 + 30 = 45 students got scholarships. Therefore, 300 - 45 = 255 senior students did not get any scholarships. The answer is 255.

Question: At the Boisjoli farm, there is a chicken coop where 270 hens and 3 roosters live. Every morning, around 8 a.m., Ms. Mosel goes to collect the eggs because, every morning, each hen lays one. Then, after 1 hour of collection, she puts all these eggs in boxes of 6. It takes her another 40 minutes. Once all this is done, Ms. Mosel brings all the boxes of eggs to her village. She does it from Monday to Sunday, because chickens don't have a day off. How many boxes does Ms. Mosel fill each week?
Answer:
First calculate the number of eggs laid in 1 week: 270 X 7 = 1890 eggs. Now let's put these eggs in the boxes: 1890 / 6 = 315 boxes. The answer is 315.
