Question

A' s income is 20% less than that of B. By what percent of B's income more than A's

Answer 1

Given, A's income is 20% less than B

Let B's income is x

A's income is x - 20% of x

= x - 20x/100

= (100x - 20x) / 100

= 80x/100

Now B's income is more than A by

= B - A

= x - 80x/100

= 20x/100

% of B's income is more than A by

= (20x/100) / (80x/100) * 100

= 20/80 * 100

= 25%
