Question: A small store made 50 posters to advertise their products. Two-fifths of them are small posters while half of them are medium posters. The rest are large posters. How many large posters are there?
Answer: 50 x 2 / 5 = 20 posters are small. And 50 / 2 = 25 posters are medium. So 20 + 25 = 45 posters are not large. Therefore, 50 - 45 = 5 posters are large. The answer is 5.
[Question]The number of goals scored in a game against Barca by exactly two players last season accounts for 20% of all goals scored in the league. If the players scored an equal number of goals, and the total number of goals scored in the league against Barca that season is 300, calculate the number of goals each of the two players scored.
[Answer]If the total number of goals scored in the league that season against Barca is 300, the two players scored 20 / 100 * 300 = 60 goals. If the players scored an equal number of goals, each scored 60 / 2 = 30 goals. The answer is 30.
Q: If Pam is currently twice as young as Rena is, and in 10 years Rena will be 5 years older than her, how old is Pam now?
A: If Rena will be 5 years older than Pam in 10 years, this means they have a 5 year age gap. Therefore, to be twice Pam's age, Rena would have to be 5 * 2 = 10 years old. This means that Pam is currently 10 - 5 = 5 years old. The answer is 5.
Question: Cody goes to the store and buys $40 worth of stuff. The taxes were 5%. After taxes, he got an $8 discount. Cody and his friend split the final price equally. How much did Cody pay?

[Question]On March 1st the sun sets at 6 PM. Every day after the sun sets 1.2 minutes later. It is 6:10 PM and 40 days after March 1st. How many minutes until the sun sets?
[Answer]The sun will set 40 * 1.2 = 48 minutes later than it does on March 1st. That means the sun will set at 6:00 + 48 = 6:48 PM. So that means the time until sunset is 6:48 - 6:10 = 38 minutes. The answer is 38.
