Reasoning and answer: There are 16 curlers in all and of them are pink or 16 curlers / 4 = 4 pink curlers. There are twice as many blue curlers as there are pink ones, so there are 4 pink x 2 = 8 blue curlers. Together, there are 4 pink curlers + 8 blue curlers = 12 pink and blue curlers in Erin's hair. The remaining curlers are green, so of the 16 total curlers 12 pink and blue curlers = 4 green curlers are in Erin's hair.
The answer: 4
What was the question?
Question: Erin put 16 curlers in her hair. One-fourth of the curlers are small pink ones. There are twice as many medium blue curlers as there are pink ones. The rest are large green curlers. How many large green curlers does Erin have in her hair?
The number of rabbits was 80 + 34 = 114. The total number of rabbits and antelopes is 114 + 80 = 194. The number of hyenas was 42 fewer than the combined number of antelopes and rabbits, which is 194 - 42 = 152. The number of wild dogs was 50 more than the number of hyenas, that is 152 + 50 = 202. The number of leopards is 1 / 2 * 114 = 57. The total number of animals Josie saw is 57 + 202 + 152 + 114 + 80 = 605.
The answer: 605
Reverse engineering the question: Josie and her family went on a safari and had an exciting time watching different animals grazing and playing together. She decided to count each animal she saw and calculated their total number. She counted 80 antelopes, 34 more rabbits than antelopes, 42 fewer hyenas than the total number of antelopes and rabbits combined, 50 more wild dogs than hyenas, and the number of leopards was half the number of rabbits. What the total number of animals that Josie counted?
Reasoning and answer: The number of parrots that flew away after the noise is 7 - 2 = 5. The same number of crows (5) flew away leaving 1 crow so there were 5 + 1 = 6 crows to begin with. The total number of crows and parrots was 7 + 6 = 13.
The answer: 13
What was the question?
Question: Seven parrots and some crows are perched on a tree branch. There was a noise and the same number of parrots and crows flew away. If only 2 parrots and 1 crow are left on the tree branch now, how many birds were perched on the branch to begin with?
First find the total wait time for the swings in minutes: 3 kids * 2 minutes / kid = 6 minutes. Then convert that number to seconds: 6 minutes * 60 seconds / minute = 360 seconds. Then find the total number of kids waiting for the slide: 3 kids * 2 = 6 kids. Then find the total wait time for the slide: 15 seconds / kid * 6 kids = 90 seconds. Then subtract the total wait for the slide from the total wait for the swings to find the difference: 360 seconds - 90 seconds = 270 seconds.
The answer: 270
Reverse engineering the question: There are 3 kids waiting for the swings and twice as many kids waiting for the slide. If each kid waits 2 minutes for the swings and 15 seconds for the slide, how many seconds shorter is the shorter wait?
Reasoning and answer: The laboratory spent 2 / 3 * 150 = 300 / 3 = $100 on test tubes. They spent a further 100 / 2 = $50 on safety gear. In all, they spent 150 + 100 + 50 = $300. Thus, 325 - 300 = $25 of the laboratory's budget remained.
The answer: 25
What was the question?
Question: A laboratory needs flasks, test tubes, and safety gear to carry out its experiments. They were given a $325 budget for the month. They bought $150 worth of flasks, spent two-thirds of that amount on test tubes, and used half of the test tube cost on safety gear. How many dollars of their budget remained?
Reasoning and answer: Lisa earned $60 * 1 / 2 = $30. Tommy earned $30 * 1 / 2 = $15. Lisa earned $30 - $15 = $15 more than Tommy.
The answer: 15
What was the question?
Question:
Lisa, Jack, and Tommy earned $60 from washing cars all week. However, half of the $60 was earned by Lisa. Tommy earned half of what Lisa earned. How much more money did Lisa earn than Tommy?
