If we take the attendance of the previous year to be 100 people, then the organizers expected this year 120 people but actual attendance was only 90 people. So actual/expected=90/120=3/4=0.75.

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%

Thanks,

Sonia ,

When it comes percentage Questions, it always good to assume a 100 as the ''base'' on which you either would decrease or increase and follow according to what is being asked.

When ever a Question of this sorts is asked , assume the ''current'' Number to be 100

Then as explained by the above two post' - a 20% Increase would 20% of 100 + 100 that would be - 120.
But then we had ONLY 90 % attending so that would be 10% of 100 - 100 : 90

90 /120 = 75 %
