Answer the following question.
Robi and Rudy contributed money to start a business that could earn them profit. Robi contributed $4000, and Rudy contributed 1/4 more money than Robi. If they made a profit of 20 percent of the total amount and decided to share the profits equally, calculate the amount of money each got.
Step-by-step reasoning process: If Robi contributed $4000, then Rudy contributed 1 / 4 * 4000 = $1000 more. The total amount of money Rudy contributed is $4000 + $1000 = $5000. Together, the contributed a total of $5000 + $4000 = $9000. They made a 20% profit, a total of 20 / 100 * $9000 = $1800. When they decided to share the profit equally, each received $1800 / 2 = $900.
The answer is 900.

Answer the following question.
John visits three different countries. He stays in the first country for 2 weeks and he spends twice as long in each of the other two countries. How much time does he spend on the trip?
Step-by-step reasoning process: He spends 2 * 2 = 4 weeks in the other two countries. So he spends 2 * 4 = 8 weeks in those countries combined. That means he is gone for 2 + 8 = 10 weeks.
The answer is 10.

Answer the following question.
It starts raining at 7:00 and pours heavily until its stops at 17:00 on a particular day. On the second day, the rain takes 2 more hours than it took on the first day to stop. On the third day, the rain pours for twice the amount of time it took on the second day. Calculate the total time it was raining in the three days.
Step-by-step reasoning process: On the first day, it rained for 17:00 - 7:00 = 10 hours. On the second day, it 10 hours + 2 hours = 12 hours for the rain to stop. It rained for 2 * 12 hours = 24 hours on the third day. In the three days, it was raining for 24 hours + 12 hours + 10 hours = 46 hours.
The answer is 46.

Answer the following question.
Aaron and his brother Carson each saved up $40 to go to dinner. The bill is 3/4 of their total money. After, they go out for ice cream. Each scoop costs $1.5 and they get the same amount as each other. If they leave with $1 in change each, how many scoops did they each buy?
Step-by-step reasoning process: They had $80 saved up because 2 x 40 = 80. They spent $60 because 80 x (3 / 4) = 60. They had $20 left for ice cream because 80 - 60 = 20. They had $2 left after leaving the ice cream shop because 2 x 1 = 2. They spent $18 on ice cream because 20 - 2 = 18. The bought 12 scoops of ice cream because 18 / 1.5 = 12. The each bought 6 scoops because 12 / 2 = 6.
The answer is 6.
