Question: The chicken crossed the road to get to the other side twice for the thrill of it. The first time, it had to dodge 23 speeding cars. The second time, a person tried to catch it and accidentally pulled out twice as many feathers as the number of cars the chicken had dodged. The chicken had 5263 feathers before its thrill-seeking road crossings. How many feathers did it have afterward?
Answer: Step-by-step reasoning process: The chicken lost 23 * 2 = 46 feathers on its second road crossing. Thus, it had 5263 - 46 = 5217 feathers after crossing the road twice.
So the answer is 5217.

Question: The big bottles of mango juice hold 30 ounces and cost 2700 pesetas each. The small bottles hold 6 ounces and cost 600 pesetas each. How many pesetas would be saved by buying a big bottle instead of smaller bottles for the same volume of juice?
Answer: Step-by-step reasoning process: The equivalent is 30 / 6 = 5 small bottles. Five small bottles at 600 pesetas each is 5 * 600 = 3000 pesetas. The savings is 3000 - 2700 = 300.
So the answer is 300.

Question: Eva learns for two semesters in a year. In 2019, she scored ten more marks in maths in the first semester than the second, 15 marks less in arts, and 1/3 marks less in science in the first semester than the second. If she got 80 marks in maths in the second semester, 90 marks in arts, and 90 in science, what's the total number of her marks in all the semesters?
Answer: Step-by-step reasoning process: In the first semester, she scored 80 + 10 = 90 marks in maths. She also scores 90 - 15 = 75 marks in arts in the first semester. She scored 1 / 3 marks less in science in the first semester than the second, which is 1 / 3 * 90 = 30. Her score in science in the first semester is 90 - 30 = 60. The total for the first semester is 90 + 75 + 60 = 225. The total for the second semester is 90 + 90 + 80 = 260. The combined marks for all the semesters in 260 + 225 = 485.
So the answer is 485.

Question: Jane had a 500 page book to read. The first half of the book Jane read with a speed of 10 pages per day, and the second half with a speed of 5 pages a day. How many days did Jane spend reading this book?
Answer:
Step-by-step reasoning process: Half of the book means 500 / 2 = 250 pages. Reading the first half took Jane 250 / 10 = 25 days. Reading the second half of the book took Jane 250 / 5 = 50 days. So in total Jane needed 25 + 50 = 75 days to read the whole book.
So the answer is 75.
