Question

Aman's income is 20% less than of Anil.How much percent is Anil's income more than Aman's income?

Answer 1

Answer:

25% more

Step-by-step explanation:

Let the income earned by Aman be denoted by x and that of Anil by y

If Aman's income is 20% less than that of Anil, then

$x=\frac{(100-20)}{100}*y\\ x=0.8y$

To get Anil's income expressed in terms of Aman's income, we make y the subject of the formula

$x=0.8y\\\frac{x}{0.8} =\frac{0.8y}{0.8}\\ Therefore;\\y=1.25x$

Therefore Anil's income is 125% of Aman's income

Thus, Anil's income is (125-100=25)% more than Aman's income
