(1)Emraan income is 25% more than that of Syed. How many per cent is Syed's income less than that of Emraan?

(2)Ram's income is 20% more than that of Lakshman. How many percent is Lakshman's income less than that of Ram?
(3)Hero's income is 20% less than that of Bill Gates. How many percent is Bill Gates's income more than that of Hero?

I will do the first one, you do the other two in the same way.

"Emraan income is 25% more than that of Syed"
---> E = 1.25*S or (5/4)S
S = E/1.25 or (4/5)E = .8E

.8 = 1 - .2 or 100% - 20%

Syed's income is 20% less than that of Emraan

To find the percentage difference in income between two individuals, you will need to calculate the percentage by which one individual's income is greater or less than the other person's income. Here's how you can solve each of the three questions:

(1) Emraan's income is 25% more than Syed's income. To find out how many percent Syed's income is less than Emraan's, we subtract Syed's income from Emraan's income and find the difference. Then we take that difference as a percentage of Emraan's income.

Let's assume Syed's income is X. The difference between Emraan's income and Syed's income is 25% of Syed's income, which is 0.25X. Therefore, Syed's income is 25% less than Emraan's income.

(2) Ram's income is 20% more than Lakshman's income. To find out how many percent Lakshman's income is less than Ram's, we subtract Lakshman's income from Ram's income and find the difference. Then we take that difference as a percentage of Ram's income.

Let's assume Lakshman's income is Y. The difference between Ram's income and Lakshman's income is 20% of Lakshman's income, which is 0.20Y. Therefore, Lakshman's income is 20% less than Ram's income.

(3) Hero's income is 20% less than Bill Gates' income. To find out how many percent Bill Gates' income is more than Hero's, we subtract Hero's income from Bill Gates' income and find the difference. Then we take that difference as a percentage of Hero's income.

Let's assume Hero's income is Z. The difference between Bill Gates' income and Hero's income is 20% of Bill Gates' income, which is 0.20Z. Therefore, Bill Gates' income is 20% more than Hero's income.

By calculating the differences as percentages of the respective incomes, we can determine the percentage difference in income between the individuals in all three scenarios.
