Reasoning and answer: Rob hunts 1 / 2 * 6 animals / day = 3 animals / day. Rob and Sam hunt 3 animals / day + 6 animals / day = 9 animals / day. Mark hunts 1 / 3 * 9 animals / day = 3 animals in a day. Peter hunts 3 * 3 animals / day = 9 animals in a day. The total they all hunt in a day is 6 animals / day + 3 animals / day + 3 animals / day + 9 animals / day = 21 animals.
The answer: 21

Question: In a day, Sam hunts 6 animals. Rob hunts half as many animals as Sam. Mark hunts 1/3 of the total of what Rob and Sam hunt. If Peter hunts 3 times as many animals as Mark does, how many animals do they all hunt in a day?
Mrs. Brown has a $125 x 10 / 100 = $12.5 discount for her purchase. So, the remaining amount she needs to pay is $125 - $12.5 = $112.5. But Mrs. Brown can still avail of the 5% discount, so she has an additional discount of $112.5 x 4 / 100 = $4.5. Therefore, Mrs. brown will only pay $112.5 - $4.5 = $108.
The answer: 108
Reverse engineering the question: It's Mother's day, so mothers get a 10% discount on the department store. Mothers who have 3 children or more can get an additional 4% off the discounted price. If Mrs. Brown has 4 children and wants to buy a pair of shoes that costs $125, how much will she pay?
Reasoning and answer: First find the number of roses needed for one ounce of perfume: 320 petals / 8 petals / rose = 40 roses. Then multiply the number of roses needed for one ounce by the number of ounces per bottle to find the number of roses per bottle: 40 roses / ounce * 12 ounces / bottle = 480 roses / bottle. Then multiply that number by the number of bottles to find the total number of roses needed: 480 roses / bottle * 20 bottles = 9600 roses. Then divide that number by the number of roses per bush to find the number of bushes Fern needs to harvest: 9600 roses / 12 roses / bush = 800 bushes.
The answer: 800
What was the question?
Question: It takes 320 rose petals to make an ounce of perfume. If each rose produces 8 petals, and there are 12 roses per bush, how many bushes will Fern have to harvest to make 20 12-ounce bottles of perfume?
Three times as many misses as hits is 3 * 50 = 150. The total number of hits and misses in the game is 150 + 50 = 200.
The answer: 200
Reverse engineering the question: There are three times as many misses as hits in an MLB game. If the number of misses is 50, how many hits and misses are made in the game?
Reasoning and answer: 7 notebooks cost 7 notebooks x $4 / notebook = $28. 2 books cost 2 books x $7 / book = $14. In total Joe has spent $28 + $14 = $42. He has $56 - $42 = $14 left.
The answer: 14
