let, total revenue = 100
40% of a club’s revenue comes from people of 25 years of age = 40
60% of its revenue comes from people of 35 years of age. = 60
the club raises its fee by 20% for its 25 years old members, so current revenue = 40*0.2 = 8
the club raises its fee by 30% for its 35 years old members, so current revenue = 60*0.3 = 18
therefore, total increase = 8+18 = 26
so, percentage increase = 26 %
correct answer is A

Let the club revenue be $100

$40 comes from people of 25 years of age

$60 comes from people of 35 years of age

The rise in fee is 20% for its 25 years old members = $8

The rise in fee is 30% for 35 years old members = $18

New increase in revenue = 8 + 18 = $26

Percentage increase in revenue = increase / Original * 100

=26/100 * 100

=26%
(option a)

The important thing is not to get entangled with the statements.

Let's see:

They do not claim that 40% of income comes from ....
In addition, 60% of the income comes from...

So we have 40% + 60% = 100% of the club's income.

We will consider that the total income of the club is 100.

So we have:

40 = 40% income of people 25 years old
60 = 60% income of 35 year olds

It is then reported that the club:
Increase your quota by 20% for people aged 25, that is:
(20/100)x40 = 0.2x40= 8

Increase your fee by 30% for people over 35, that is:

(30/100)x60 = 0.3x60=18

Then the percentage increase is 8 + 18 = 26%

Answer A

Interesting question: what percentage is the non-increase of 25-year-olds compared to the non-increase of 35-year-olds?

Come on dare, you can!
