Green grapes = G. Red grapes = 3G + 7. Raspberries = G - 5. G + 3G + 7 + G - 5 = 102. 5G + 2 = 102. 5G = 100. G = 20. 3 * 20 + 7 = 67. There are 67 red grapes.
The answer: 67
Reverse engineering the question: In a fruit salad, there are raspberries, green grapes, and red grapes. There are seven more than 3 times the number of red grapes as green grapes. There are 5 less raspberries than green grapes. If there are 102 pieces of fruit in the salad, how many red grapes are in the salad?
Reasoning and answer: If Pedro has three times more gumballs than Alicia, he has 3 * 20 gumballs = 60 gumballs more. In total, Pedro has 20 gumballs + 60 gumballs = 80 gumballs. When they put their gumballs together, the total number of gumballs in the bowl becomes 20 gumballs + 80 gumballs = 100 gumballs. Pedro takes out 40% of the gumballs which is 40 / 100 * 100 gumballs = 40 gumballs. The number of gumballs remaining is 100 gumballs - 40 gumballs = 60 gumballs.
The answer: 60

Question: Alicia has 20 gumballs. Pedro has that many gumballs plus an additional number of gumballs equal to three times the number Alicia has. They put their gumballs in a bowl, and later Pedro takes out 40% of the gumballs to eat. How many gumballs are remaining in the bowl?
At 5 cents a minute, calling his father cost Freddy 5 * 45 = 225 cents. At 25 cents a minute, calling his brother cost Freddy 25 * 31 = 775 cents. Adding the cost of calling his father and brother, we find that Freddy paid a total of 225 + 775 = 1000 cents. Since each dollar has 100 cents, Freddy paid 1000 / 100 = 10 dollars.
The answer: 10
Reverse engineering the question: Freddy is calling his family on New Year's Eve. He calls his dad, who lives in the same city as him, and they talk for 45 minutes. Then he calls his brother, who lives on the other side of the world, and they talk for 31 minutes. Local calls cost 5 cents a minute, while international calls cost 25 cents a minute. How many dollars did Freddy spend calling his family on New Year's Eve?
Reasoning and answer: If Emily adds 5 more oranges, there will be a total of 10 + 5 + 5 = 20 fruits in the basket. So, the percentage of the fruit that is apples is 10 / 20 x 100% = 50%.
The answer: 50
