Question

A's income is $20\%$ less than that of B's. How much percent is B's income is more than A's?

Answer 1

Let B's income $=Rs.100$

Then A's income $=$ B's income $-20\%$ of B's Income

A's income $=100-\frac{20}{100}\times 100=100-20=80$

Now, B's income is $Rs.20$ more than A

$\Rightarrow \frac{20}{80}\times 100=25\%$ more than A's income
