Question

Last year, the number of students at RSM increased by 100%. This year, the number of students increased by 150%. What percent of the number of students now equals the number of students two years ago?.

Answer 1

Answer:

increasing by N% means the new value is 1+N/100 as much as the old value. So, we have

new = old*(1+1)(1+1.5) = 5.00 * old so, old = new/5 or 20%
