Reasoning and answer: One less than 5 is 5 - 1 = 4. If one tarantula egg sac can contain 1000 tarantulas, then four egg sacs can hold 4 * 1000 = 4000 tarantula babies. If each tarantula baby has eight legs, the 4 egg sacs can contain 4000 * 8 = 32,000 baby tarantula legs.
The answer: 32000

Question: If a tarantula has eight legs, and one tarantula egg sac can contain 1000 tarantulas, how many baby tarantula legs would be in one less than 5 egg sacs?
There were 120 / 3 = 40 men at the party. There were 120 / 2 = 60 women at the party. So, there were 40 + 60 = 100 men and women at the party. Thus, 120 - 100 = 20 were children.
The answer: 20
Reverse engineering the question: Out of the 120 people who attended the party, 1/3 are men while half are women. The rest are children. How many children attended the party?
Reasoning and answer: The sell reduced the price of each pin by 20 * .15 = $3. So he paid 20 - 3 = $17 per pin. So the total cost was 17 * 10 = $170.

His annual salary for the first year of working is 6000 x 12 = $72000. Kirt's monthly increase is $6000 x 30 / 100 = $1800. So, he received $6000 + $1800 = $7800 monthly on the second and third year of working. Kirt's annual salary in the second and third year was $7800 x 12 = $93600. . Thus, his total earning after 3 years is $72000 + $93600 + $93600 = $259200.
The answer: 259200
Reverse engineering the question: Kirt has a $6000 monthly salary when he started his job. After a year of working, his salary increased by 30%. How much are his total earnings after 3 years?
Reasoning and answer: First find the cost of two slices of bread: $0.15 / slice * 2 slices = $0.30. Then add the cost of one slice each of ham and cheese: $0.30 + $0.25 + $0.35 = $0.90.
The answer: 90

Question: Joe sells ham and cheese sandwiches for $1.50. If a slice of bread costs $0.15, a slice of ham costs $0.25 and a slice of cheese costs $0.35, how many cents does a sandwich with one slice of each protein cost Joe to make?
Reasoning and answer: If the 12 students had shared the 108 oranges, each student would have gotten 108 / 12 = 9 oranges. But 36 were removed so there are 108 - 36 = 72 oranges left. So 12 shared 72 for each to get 72 / 12 = 6 oranges. This is 9 - 6 = 3 less than they would each get if they did not have to throw any orange away.
The answer: 3

Question:
A class of 12 students was about to share 108 oranges equally among themselves when it was discovered that 36 of the oranges were bad and had to be thrown away. How many oranges less will each student get now than if no orange had to be thrown away?
