Q: Ral is twice as old as Suri. In 3 years, Suri's current age will be 16. What is Ral's current age?
A: If Suri will be 16 in 3 years, that means she is 16 - 3 = 13 years old now. Rai is twice as old as Suri, so she is 2 * 13 = 26 years old now. The answer is 26.
Question: Tom charges a fee of $100 a day to search for an item for the first 5 days and then $60 per day for every day after that. How much did it cost for him to look for an item for 10 days?
Answer: The first 5 days cost 5 * 100 = $500. He gets 10 - 5 = 5 days on discount. He paid 5 * 60 = $300 at the discounted rate. So in total he pays 500 + 300 = $800. The answer is 800.
[Question]Hillary always buys the Wednesday, Thursday and Friday editions of the local newspaper for $0.50 each. On Sunday, she spends $2.00 to get that copy. How much does she spend on the newspaper over 8 weeks?
[Answer]She buys Wednesday, Thursday and Friday's paper for $0.50 each so that's 3 * .50 = $1.50. She spends $1.50 for the weekday papers and $2.00 for the Sunday paper for a total of 1.5 + 2 = $3.50 a week. Over 8 weeks she spends 8 * 3.5 = $28.00. The answer is 28.
Q: In 5 years, Nacho will be three times older than Divya. If Divya is currently 5 years old, what's the sum of their ages now?
A: If Divya is currently 5 years old, she will be 5 + 5 = 10 years old in five years. Since in 5 years Nacho will be three times older than Divya, he will be 3 * 10 = 30 years older than Divya. Nacho's total age in five years will be 30 + 10 = 40 years. Currently, Nacho is 40 - 5 = 35 years old. The sum of Divya and Nacho's age now is 35 + 5 = 40 years. The answer is 40.
Question: Mark is filling a punch bowl that can hold 16 gallons of punch. He fills it part way, then his cousin comes along and drinks half the punch in the bowl. Mark starts to refill the bowl and adds 4 more gallons, but then his friend Sally comes in and drinks 2 more gallons of punch. After that, Mark has to add 12 gallons of punch to completely fill the bowl. How much punch did Mark initially add to the bowl?
Answer: First, figure out how much punch was left in the bowl before Mark refilled it by subtracting the 12 gallons he added from the bowl's total capacity: 16 - 12 = 4 gallons. Next, figure out how much punch was in the bowl before Sally came along: 4 + 2 = 6 gallons. Next, figure out how much punch was in the bowl before Mark started to refill it: 6 - 4 = 2 gallons. Finally, multiply that amount by 2 to find out how much punch there was before the cousin drank half: 2 * 2 = 4 gallons. The answer is 4.
Q: Peggy is moving and is looking to get rid of her record collection. Sammy says that he will buy all of them for 4 dollars each. Bryan is only interested in half of the records but will offer 6 dollars each for the half that he is interested in and 1 dollar each for the remaining half that he is not interested in with the hopes that he can resell them in bulk later. If Peggy has 200 records, what is the difference in profit between Sammy versus Bryan's deal?
A:
Sammy is offering to take the whole collection of 200 records and pay Peggy 4 dollars each for them which would net Peggy 200 * 4 = 800 dollars for her entire record collection. Bryan is willing to buy Peggy's entire record collection but at two different price points, half at one point and half at another. Half of Peggy's record collection is 200 / 2 = 100, which means that 100 records will sell for one price and 100 records will sell for another price. Bryan is willing to pay more for the half of the record collection that he is interested in so Peggy would net 100 * 6 = 600 dollars for the first half of her record collection. For the half of the collection that Bryan is just planning on reselling at a later date, he is willing to offer Peggy 100 * 1 = 100 dollars to take off of her hands. In total Bryan is willing to offer Peggy 600 + 100 = 700 dollars for her entire record collection. If Sammy is offering 800 dollars to buy Peggy's entire record collection and Bryan is offering 700 dollars for Peggy's entire record collection, then Peggy's net profit would be 800 - 700 = 100 dollars more by taking Sammy's deal instead of Bryan's deal. The answer is 100.
