Reasoning and 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: 5

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: 30
Reverse engineering the 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.


Reasoning and answer: 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: 5

Question: 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?


The taxes were 40 * .05 = $2. So the price was 40 + 2 = $42. He got a discount so the price he paid was 42 - 8 = $34. Since he paid half his price was 34 / 2 = $17.
The answer: 17
