[Question]An investor invested some money in 2 separate schemes: A and B. Scheme A will yield 30% of the capital within a year, and scheme B will yield 50% of the capital within a year. If he invested $300 in scheme A and $200 in B, how much more money will he have in scheme A than in B after a year, provided he does not withdraw anything?
[Answer]After a year, scheme A will yield 30% of his capital which is (30 / 100) * $300 = $90. In addition to his capital, he will have $90 + $300 = $390 in scheme A. After a year, scheme B will yield 50% of his capital which is (50 / 100) * $200 = $100. In addition to his capital, he will have $100 + $200 = $300 in scheme B. After a year, he will have $390 - $300 = $90 in scheme A more than in scheme B. The answer is 90.
Q: Jason has a moray eel that eats 20 guppies a day and 5 betta fish who each eat 7 guppies a day. How many guppies per day does she need to buy?
A: First find the total number of guppies the betta fish need: 5 fish * 7 guppies / fish = 35 guppies. Then add the number of guppies the eel needs to find the total number needed: 35 guppies + 20 guppies = 55 guppies. The answer is 55.
Question: Elida has 5 letters while Adrianna has 2 less than twice the number of letters Elida has. What's 10 times the average number of letters in both names?
Answer: Twice the number of letters Elida has is 2 * 5 = 10. 2 less than twice the number of letters Elida has is 10 - 2 = 8. The total number of letter in both names is 8 + 5 = 13. The average number of letters in the name Elida and Adrianna is 13 / 2 = 6.5. 10 times the average number of letters in both names is 10 * 6.5 = 65. The answer is 65.
[Question]James takes 5 oranges and breaks each orange into 8 pieces. He splits the pieces between 4 people. If an orange has 80 calories how many calories does each person get?
[Answer]He makes 5 * 8 = 40 pieces. So each person gets 40 / 4 = 10 pieces. That means each person eats 10 / 8 = 1.25 of an orange. So each person eats 80 * 1.25 = 100 calories of orange. The answer is 100.
