Can any one help me to understand this Question?
In the current year the audience was expected to increase by 20 % more than the the previous year.
let the previous year attendance be 100, so now it is expected to increase to 120% of 100 which is 120
However there was a drop of 10% in people who actually attended , so instead of 120% of (current yearr) 90% of (current year ) came, so basically 90 people came
The question asks us to find how much is 90 as a percentage of 120 which is 75%
