it so simple
A = x% of Y = xy/100.
B = Y% of X = xy/100.
Hence A = B.
A = x% of Y = xy/100.
B = Y% of X = xy/100.
Hence A = B.

It's Simple
Let's take x =10 & y=500.
So, A = x% of y & B = y% of x.
Just put the values:
A = (10%/100) * 500 = 50 &
B = (500%/100) * 10 = 50,
Hence A = B.

B = (500%/100) * 10 = 50,
Hence A = B.

@Abhishek
Total increase 6300 - 5500 = 830.
Males = 11%.
Females = 20 % = 11 % + 9%
11 % of 5500 = 605.
So,
9 % of females = 830 - 605.
= (225/9) * 100 = 2500.
Total increase 6300 - 5500 = 830.
Males = 11%.
Females = 20 % = 11 % + 9%
11 % of 5500 = 605.
So,
9 % of females = 830 - 605.
= (225/9) * 100 = 2500.

It is only true if you assume x=y.

Hello, guys as a beginner think very straight and you'll get the answer.
The way it is mentioned just write it and solve:
A= X% of Y.
Similarly ;
B = Y% of X.
According to the percentage formula;
AX/Y * 100.
BY/X * 100.
AX/Y = BY/X.
Just cancel X and Y according to simple multiplication rule. And only left it A = B.
And as it is not given in the option hence option E.

A=x% of y,
= y * (x/100).
B= y% of x,
= x * (y/100).
= y * (x/100).
B= y% of x,
= x * (y/100).
