Q: The ratio of boys to girls at the dance was 3:4. There were 60 girls at the dance. The teachers were 20% of the number of boys. How many people were at the dance?
A: 60 girls represent 4 parts, so one part of students is 60 / 4 = 15 students. There are 15 * 3 = 45 boys at the dance. The teachers at the dance are 45 * 0,2 = 9 teachers at the dance. There are 60 + 45 + 9 = 114 people at the dance. The answer is 114.
Question: Mario's salary increased by 40% to $4000 this year. Bob's salary from last year was equal to three times Mario's salary this year. If Bob's current salary is 20% more than his salary last year, what is his current salary?
Answer: Last year, Bob's salary was equal to three times Mario's salary this year, meaning Bob was earning 3 * $4000 = $12000. If Bob's salary increased by 20% this year, he is earning 20 / 100 * $12000 = $2400 more. Bob's total salary this year is $12000 + $2400 = $14400. The answer is 14400.

Question: Maria gave a third of her money to her friend Isha, half of what she gave to Florence. If Florence received three times as much money as Maria's cousin Rene, and Rene received $300, how much money did Maria give her three friends?

Half the floors are full, so there are 12 floors * 0.5 = 6 floors that are full. So the full floors contain 6 floors * 10 apartments = 60 apartments. The remaining floors are at half - capacity, so there are 12 floors – 6 full floors = 6 half - full floors. Each of these floors therefore contains 10 apartments * 0.5 = 5 apartments. So on the half - full floors, there are a total of 6 floors * 5 apartments = 30 apartments. In total, there are 30 + 60 = 90 filled apartments in the building. This means there are 90 apartments * 4 people per apartment = 360 people in the building. The answer is 360.
