Reasoning and answer: If the final number of geese was 12, which included the 4 that joined from the trees, then before these 4 joined, there were 12 - 4 = 8 geese in the sky. Since these 8 geese represent the half of geese remaining, then the initial formation contained 8 * 2 = 16 geese.
The answer: 16

Question: Albert noticed a flock of geese flying together in a V formation in the sky overhead. One half of the geese broke off from the formation, flew toward the earth, and landed in some trees. Then, 4 geese flew up, out of the trees, and joined those already flying in the air to make a new V formation in the sky. If the final number of geese flying in the V formation was 12, how many geese were in the first formation Albert noticed in the sky?


Krishna won 3 / 4 * 8 rounds = 6 rounds. If they played eight rounds, Callum won 8 rounds - 6 rounds = 2 rounds. If a round earns one 10 points, Callum got 2 rounds * 10 points / round = 20 points.
The answer: 20
Reverse engineering the question: Krishna and Callum are playing a game where they earn 10 points if they win any round. If they played eight matches and Krishna won 3/4 of the matches, what is the total number of points that Callum earned?


Reasoning and answer: If the TV's original price was $500, at the auction, its price increased by 2 / 5 * $500 = $200. The total price at which the TV was sold at the auction is $500 + $200 = $700. The price of the phone also increased at the action, a 40% increase which is 40 / 100 * $400 = $160. The total price that the phone was sold for after the auction is $400 + $160 = $560. In total, the TV and the phone sold for $700 + $560 = $1260 at the auction.
The answer: 1260
What was the question?
Question: At an auction event, the price of a TV, whose cost was $500, increased by 2/5 times its initial price. The price of a phone, which was $400, also increased by 40% from its original price. If Bethany had taken both items to the auction, calculate the total amount she received for the items after the sale at the auction.


If the car traveled from Ningi to Zipra in 80% of the time it traveled from Ngapara to Zipra, it took 80 / 100 * 60 = 48 hours to travel from Ningi to Zipra. The total travel time that day is 48 + 60 = 108 hours.
The answer: 108
Reverse engineering the question: On a particular day, a car traveled from Ningi to Zipra in 80% of the time it traveled from Ngapara to Zipra. If the car took 60 hours to travel from Ngapara to Zipra, calculate the total time the car traveled that day.


Reasoning and answer: A pen costs $9 more than $2 which is $9 + $2 = $11. Altogether they cost $11 + $2 = $13.
The answer: 13

Question: A pen costs $9 more than a pencil. If a pencil costs $2, find the total cost of both items.


Reasoning and answer: The cost of the popcorn is $5 x 80 / 100 = $4. The cost of a can of soda is $4 x 50 / 100 = $2. The cost of 4 tickets is $5 x 4 = $20. The cost of 2 sets of popcorn is $4 x 2 = $8. The cost of 4 cans of soda is $2 x 4 = $8. Therefore, the family paid a total of $20 + $8 + $8 = $36.
The answer: 36
