B's Income is 100, A's income is 20% Less than B's, A's income will be 80% of 100— i.e. 80. Now,if A 's income is compared to B's , it is 20 % more than A, ,from B's perspective, but from A's Perspective, B has 20 more than his 80, and it is 25% of 80.

Answer:

A= Income of Person A

B = Income of Person B

A = (1.00-0.20)×B

(1.00 because in this step we consider B as the 100%, and 0.20 because A earns 20% less than B)

=> A = 0.80 B

That's how you get the value of A.

Now imagine you didn't have the information that A is 80% of B, but the value of A.

To calculate the 0.80, you would do the following:

A/B = percentage

You divide A with B to know what percentage of B it is.

And this is exactly how we will calculate the other percentage, the one you asked for. You divide B with A. And we already know A, right? It's 0.80B, we already got that one.

So it’s:

B/0.80B = 1.00B/0.80B = 1.00/0.80 = 1.25

Here we assumed, that A is the 100%, so B is the 125%

125% - 100% = 25%

=> B earns 25% more money than A. Nice job, B.
