Question: A truck can carry a maximum of 13,500 kgs of supplies. Yesterday, the truck was loaded with 100 boxes that weigh 100 kgs each. Then, it was loaded with 10 crates which weigh 60 kgs each. Today, it was loaded again with 50 sacks which weigh 50 kilograms each. How many bags weighing 40 kilograms each can we still load in the truck?
Answer: The total weight of the boxes is 100 boxes x 100 kg / box = 10 000 kg. The total weight of the crates is 10 crates x 60 kg / crate = 600 kg. The total weight of the sacks is 50 sacks x 50 kg / sack = 2 500 kg. So, the total weight of the supplies that were already loaded is 10,000 kg + 600 kg + 2500 kg = 13,100 kg. Hence, the most weight that can still be loaded in the truck is 13,500 kg - 13,100 kg = 400 kg. This means 400 kg / 40 kg / bag = 10 bags can still be loaded in the truck. The answer is 10.
[Question]Out of the 300 comic books in a comic store, 30% are liked by females, males like 120, and both genders don't like the rest. What percentage of the comic books are disliked by both males and females?
[Answer]The number of comic books that females like is 30 / 100 * 300 = 90 books. Together, both males and females like 90 + 120 = 210 comic books. The number of comic books that are disliked by both males and females is 300 - 210 = 90. The percentage of books that are disliked by both genders is 90 / 300 * 100 = 30%. The answer is 30.
Q: A pack of pretzels costs $4, while a pack of chips is 75% more expensive. Maciek went and bought two packets of chips and two packets of pretzels. How much did he pay for his purchases?
A: One pack of chips is 75 / 100 * 4 = $3 more expensive than a pack of pretzels. That means one pack of chips costs 4 + 3 = $7. So Maciek paid 4 * 2 = $8 for the pretzels. He also paid 7 * 2 = $14 for the chips. In total Maciek paid 8 + 14 = $22 for his purchases. The answer is 22.
Question: Hakeem has always loved artichoke dip and plans to make it this weekend. He has $15 dollars to buy artichokes and can find the rest of the ingredients at home. It takes 3 artichokes to make 5 ounces of dip. How many ounces can he make if artichokes cost $1.25 each?
Answer: He can buy 12 artichokes because 15 / 1.25 = 12. Each artichoke makes 5 / 3 ounces of dip because there are 3 artichokes per 5 ounces. He can make 20 ounces of dip because 12 x (5 / 3) = 60 / 3 = 20. The answer is 20.
[Question]There are 3 numbers that are consecutive integers. Together they have a sum of 18. What is the largest of the 3 numbers?
[Answer]Let N = smallest number. N + 1 = next number. N + 2 = largest number. N + (N + 1) + (N + 2) = 18. 3N + 3 = 18. 3N = 15. N = 5. The largest number is 7. The answer is 7.
[Question]Susan, Arthur, Tom and, Bob are siblings. Arthur is 2 years older than Susan, and Tom is 3 years younger than Bob. If Bob is 11 years old, and Susan is 15 years old, how old are all four family members in total?
[Answer]
Arthur is 2 years older than Susan, so he is 15 + 2 = 17 years old. Bob is 11 years old, so Tom is 11 - 3 = 8 years old. So in total these four family members have 11 + 15 + 17 + 8 = 51 years. The answer is 51.
