Reasoning and answer: Mr. Mayer wants to get a $1000 x 30 / 100 = $300 profit. So, he will sell each Corgi dog for $1000 + $300 = $1300. Hence, his friend should pay $1300 x 2 = $2600.
The answer: 2600

Jacob ate 8 – 3 = 5 pies. Noah ate 5 * 3 = 15 hotdogs. The total weight of the hotdogs was 15 * 2 ounces = 30 ounces.
The answer: 30
Reverse engineering the question: Mason, Noah and Jacob want to have an eating contest but can't agree on what food to eat. Mason wants hot dogs, Noah insists on burgers, and Jacob thinks they should eat pies. They finally agree that everyone can eat whatever they want and they'll use the weight of the food to determine who wins. A hot dog weighs 2 ounces, a burger weighs 5 ounces, and a pie weighs 10 ounces. Jacob eats three fewer pies than Noah eats burgers. Mason eats 3 times as many hotdogs as the number of pies consumed by Jacob. If Noah ate 8 burgers, what is the total weight of the hotdogs that Mason ate?


Reasoning and answer: The gummy bears cost 10 * 2 = $20. The chocolate chips cost 5 * 20 = $100. The total cost for these two is 100 + 20 = $120. The chocolate bars in total cost 150 - 120 = $30. A single chocolate bar costs 30 / 10 = $3.
The answer: 3

Ten years from now, the elder child will be 20 + 10 = 30 years old. If the elder child is 20 years old now, the second born is 20 - 5 = 15 years old, 5 years younger than the firstborn. The second - born will be 15 + 10 = 25 years old ten years from now. The total age of the first and second - born 10 years from now will be 25 + 30 = 55. The third - born who is five years younger than the second born is 15 - 5 = 10 years old. The third sibling's age ten years from now will be 10 + 10 = 20 years old. The total age of the three siblings ten years from now will be 55 + 20 = 75 years.
The answer: 75
Reverse engineering the question: Three siblings are born 5 years apart, each. If the eldest child is 20 years old now, what's the total of the ages of the three siblings 10 years from now?
