[Question]Alannah, Beatrix, and Queen are preparing for the new school year and have been given books by their parents. Alannah has 20 more books than Beatrix. Queen has 1/5 times more books than Alannah. If Beatrix has 30 books, how many books do the three have together?
[Answer]If Beatrix has 30 books, Alannah has 30 books + 20 books = 50 books. Queen has 1 / 5 * 50 books = 10 more books than Alannah. The total number of books Queen has is 50 books + 10 books = 60 books. All three have 60 books + 50 books + 30 books = 140 books together. The answer is 140.
Q: A father and a son start approaching each other at the same time from opposite ends of a hallway that is 16m long. If the father is walking three times as fast as the son, at what distance from the father's end of the hallway will they meet?
A: Since the father is walking 3 times as fast as his son, their speeds are in a ratio of 3:1 respectively. They started at the same time so they will cover distance at the same ratio of 3:1. Each portion of the distance they covered is 16 / (3 + 1) = 4m. The father covered three portions of the distance which is 3 * 4m = 12m from his end. The answer is 12.
Question: Leila went to the supermarket to get some groceries. Then she headed to her mechanic to get her automobile fixed. If fixing her automobile cost $350 which was $50 more than thrice the amount she spent at the supermarket, how much has she spent altogether?
Answer: Reversing the steps to obtain the amount she spent at the supermarket, $50 less than $350 is $350 - $50 = $300. If $300 was thrice the amount she spent at the supermarket, then the amount spent at the supermarket was $300 / 3 = $100. In addition to what she spent fixing her auto, she spent $100 + $350 = $450 altogether. The answer is 450.
[Question]The price of a monster box of cereal is reduced by $24 after an oversupply in the market. If the initial price was $104, and Romina bought 20 of such boxes, calculate the total price she paid.
[Answer]If the initial price was $104, and the price of the monster box of cereal reduced by $24, the new price is $104 - $24 = $80. If Romina bought 20 such boxes, he paid 20 * $80 = $1600. The answer is 1600.
[Question]James buys 2 puzzles that are 2000 pieces each. He anticipates for these larger puzzles he can do 100 pieces every 10 minutes. So how long would it take to finish both puzzles?
[Answer]
His speed means he can do 10 / 100 = .1 minute per piece. So he can finish 1 puzzle in 2000 * .1 = 200 minutes. So these two puzzles take 200 * 2 = 400 minutes. The answer is 400.
