It takes 10 * 1.5 = 15 hours to fix his shirts. It takes 1.5 * 2 = 3 hours per pair of pants. So it takes 3 * 12 = 36 hours for the pants. That means in total it takes 15 + 36 = 51 hours. So it cost 51 * 30 = $1530 to fix everything.
The answer: 1530
Reverse engineering the question: James hires a seamstress to fix all his shirts and pants. He has 10 shirts and 12 pairs of pants. It takes 1.5 hours to fix a shirt and twice as long for pants. The tailor charges $30 per hour. How much does it cost?
Reasoning and answer: Eunice can plant a total of 3 pots x 3 seeds = 9 seeds in three pots. So, only 10 - 9 = 1 eggplant seed will be planted in the fourth pot.
The answer: 1
What was the question?
Question: Eunice has 10 eggplant seeds and 4 pots. How many seeds will be planted in the fourth pot if 3 seeds can be planted in 1 pot?
John plays in 20 * .8 = 16 games. That means he gets fouled 16 * 5 = 80 fouls. So he gets 80 * 2 = 160 foul shots. So he makes 160 * .7 = 112 free throws.
The answer: 112
Reverse engineering the question: John hits 70% of his free throws. For every foul he gets 2 shots. He gets fouled 5 times a game. How many free throws does he get if he plays in 80% of the 20 games the team plays?
Reasoning and answer: In 64 fluid ounces, there are 64 / 8 = 8 eight - ounce servings. Using 16 - ounce servings, Simeon now drinks 64 ounces in 64 / 16 = 4 servings. Thus, Simeon now drinks his water in 8 - 4 = 4 fewer servings per day.
The answer: 4
What was the question?
Question: Simeon drinks 64 fluid ounces of filtered water every day. He used to drink this water in 8-ounce-servings. But now, he drinks his water in 16-ounce servings. How many fewer servings per day does it now take Simeon to drink his water than it used to?
Archie needs $3 x 3 = $9 per day to buy 3 antibiotics. Therefore Archie needs $9 x 7 = $63 to buy antibiotics that will last for a week.
The answer: 63
Reverse engineering the question: Archie received his medical receipt from his doctor, and he needs to take antibiotics three times a day. If antibiotic costs $3 each and he needs to take it for a week, how much money does he need to buy the antibiotics?
If Ariella has $200 more in her son's saving account than Daniella has, then she has $400 + $200 = $600. If she earns an interest of 10% in the first year, her savings account increases by 10 / 100 * $600 = $60. In the second year, she earns the same amount of interest, which $60 + $60 = $120. The total amount of money in Ariella's account after two years is $600 + $120 = $720.
The answer: 720
Reverse engineering the question:
Ariella has $200 more in her son's saving account than Daniella has in her son's savings account. Ariella's account earns her simple interest at the rate of 10% per annum. If Daniella has $400, how much money will Arialla have after two years?
