If Ernie's income is 4 / 5 of what it used to be, she is earning 4 / 5 * $6000 = $4800 now. Jack's income is now twice what Ernie used to make a total of 2 * $6000 = $12000. Combined, Ernie and Jack are making $12000 + $4800 = $16800.
The answer: 16800
Reverse engineering the question: Ernie's income is 4/5 of what it used to be and Jack's income is now twice what Ernie used to make. How much do they earn combined if Ernie used to make $6000?
Reasoning and answer: First, find the number of dog nails by multiplying the number of dogs by the number of nails on each leg and the number of legs on each dog: 4 dogs * 4 legs per dog * 4 nails per leg = 64 nails. Then do the same for parrots, ignoring the one parrot's extra toe for now: 8 parrots * 2 legs per parrot * 3 nails per leg = 48 nails. Now add one to the previous number because one parrot has an extra toe: 48 + 1 = 49 nails. Now add the number of nails from the parrots and the dog: 49 nails + 64 nails = 113 nails.
The answer: 113
What was the question?
Question: Cassie is trimming her pet's nails. She has four dogs and eight parrots. Each dog has four nails on each foot, and each parrot has three claws on each leg, except for one parrot who has an extra toe. How many nails does Cassie need to cut?
Ahmed has 4 times as many apple trees as Hassan who has 1 apple tree so Ahmed has 4 * 1 = 4 apple trees. Ahmed has 8 orange trees in addition to the apple trees for a total of 8 + 4 = 12 trees. Hassan has 1 + 2 = 3 trees in his orchard. Ahmed has 12 - 3 = 9 more trees than Hassan.
The answer: 9
Reverse engineering the question: Ahmed has 8 orange trees and four times as many apple trees in his orchard as Hassan. If Hassan has one apple tree and two orange trees, and they both have only apple and orange trees in their orchards, how many more trees are in Ahmed's orchard than in Hassan's?
Reasoning and answer: She made $2.5 from hitting drums because 10 - 7.5 = 2.5. She hit 200 drums to start making money. She hit 100 drums in order to make the $2.5 because 2.5 / .025 = 100. She hit 300 drums in total because 100 + 200 = 300.
The answer: 300
What was the question?
Question: Juanita enters a drumming contest. It costs $10 to enter. She has 2 minutes to hit as many drums as she can. If she hits 200 drums, she can start to make money, equal to 2.5 cents for every drum hit. How many drums does she hit if she lost $7.5 for joining the contest?
When Dianne turns 30, Alex will be 30 x 2 = 60 years old. Allison will be 30 / 2 = 15 years old then. Dianne will turn 30 in 30 - 16 = 14 years. Currently, the age of Alex is 60 - 14 = 46. Currently, Allison is 15 - 14 = 1 year old. So, the sum of Alex and Allison's ages now is 46 + 1 = 47 years old.
The answer: 47
Reverse engineering the question: When Diane turns 30, she will be half the age of Alex and twice as old as Allison. Diane is 16 years old now. What is the sum of the ages of Alex and Allison now?
There are 15 - 6 = 9 students who like French fries only. There are 10 - 6 = 4 students who like burgers only. So, 9 + 4 + 6 = 19 students like either French fries, burgers, or both. Hence, 25 - 19 = 6 students do not like either fries or burgers.
The answer: 6
Reverse engineering the question:
In a class of 25 students, students were asked if they like French fries, burgers, or neither. 15 students said they like French fries and 10 said they like burgers, with these statistics including the responses of 6 students who said they like both French fries and burgers. How many students do not like either food?
