Question: Alvin is 30 years old and Simon is 5 years away from being 1/2 the age of Alvin. How old is Simon?
Answer: Step-by-step reasoning process: 1 / 2 the age of Alvin who is 30 is 30 / 2 = 15. Simon is 5 years away from being half the age of Alvin so Simon is 15 - 5 = 10 years old.
So the answer is 10.

Question: A ship left a port and headed due west, having 400 pounds of food for the journey's supply. After one day of sailing, 2/5 of the supplies had been used by the sailors in the ship. After another two days of sailing, the sailors used 3/5 of the remaining supplies. Calculate the number of supplies remaining in the ship to last the sailors until they dock.
Answer: Step-by-step reasoning process: After one day of sailing, 2 / 5 * 400 = 160 pounds of food supplies had been used. The total number of supplies remaining in the ship is 400 - 160 = 240 pounds. After another 2 days of sailing, 3 / 5 * 240 = 144 pounds of food had been used. The total number of supplies remaining in the ship is now 240 - 144 = 96 pounds.
So the answer is 96.

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?
Answer: Step-by-step reasoning process: 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.
So the answer is 60.
