Question

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

Answer 1

Let Anil's income be x.
Then, Aman's income \[= x - \frac{20x}{100}\]
\[ = \frac{8x}{10}\]
Difference in the incomes of Anil and Aman \[= x - \frac{8x}{10}\]
\[ = \frac{2x}{10}\]
∴ Percentage of the difference in the incomes of Anil and Aman to that of Aman's income \[= \left( \frac{2x}{10} \right)/\left( \frac{8x}{10} \right) \times 100\]
\[ = \frac{1}{4} \times 100\]
\[ = 25 \%\]
