@Rashal.
Let total no of members are in club = x
40% are female = (40/100) * x.
Then new 40 male members are add in the club.
So, now total no of member are in club = x + 40.
Now the % of female members dropped to 30%
So no of females are = (30/100) * (x+40).
Now 40/100) * x = (30/100) * (x+40).
X = 120.
Then female members are = 40/100) * 120.
= 48 (ans).

According to me,
Let's take A=2.
and B=3.
Then A%B=2%3= 2*3/100 = 6/100.
and B%A= 3%2= 3*2/100 = 6/100.
I answer is xy=xy not x=y.

let x=50 and y=100;
A=x % 0f y.
=100 of 50%.
=50.
B=y % of X.
= 50 0f 100%.
=50.
A=B.
A=x % 0f y.
=100 of 50%.
=50.
B=y % of X.
= 50 0f 100%.
=50.
A=B.

Why not. U are confused, here is the short cut.
10%of 450 is 45 then
40%of 450 will be 45*4=180.
