Consider the Q and A. Q: There are 20 students in a class. Only one-fourth of the students stayed in the classroom while the rest went to the playground. Of those who went to the playground, one-third are boys. How many girls are there on the playground from this class?
A: 10
What is the step-by-step reasoning process?
Step-by-step reasoning process: Out of the 20 students, 20 x 1 / 4 = 5 students stayed in the classroom. While 20 - 5 = 15 students went to the playground. Out of these 15 students, 15 x 1 / 3 = 5 are boys. Therefore, 15 - 5 = 10 girl students from this class are in the playground.

Consider the Q and A. Q: A floral shop had a three day sale on rose bouquets. On Monday, they sold 12 bouquets. On Tuesday, they sold three times that many bouquets. On Wednesday it rained all day and they only sold a third of what they did the day before. How many bouquets did they sell during the three day sale?
A: 60
What is the step-by-step reasoning process?
Step-by-step reasoning process: On Tuesday they sold 12 * 3 = 36 bouquets. On Wednesday they only sold 36 / 3 = 12 bouquets. In total they sold 12 + 36 + 12 = 60 bouquets.

Consider the Q and A. Q: A vampire needs to suck 7 gallons of blood per week to survive. If he sucks 2 pints of blood per person, how many people does he need to suck each day to survive?

Step-by-step reasoning process: Each day it needs to consume 7 / 7 = 1 gallon of blood. There are 128 / 16 = 8 pints per gallon. So he needs to suck blood from 8 / 2 = 4 people per day.
