Question

During last year the number of students in RSM increased by 100%. This year, the number of students increased by 150%. What percent of the number of students now was the number of students two years ago?

Answer 1

Answer:20%

Step-by-step explanation:so we start with x as the year before. then we get 2x from 100%. this year it would be 2x times 150% which is equal to 3x added to the year before. That would be 5x. 5x compared to x people would think is 500% but it is switched the other way to 20%.
