Verified Answer
If A's income is 25% more than B's income and B's income 20% more than...
Let salary of C is 100.
Therefore salary of B is 20% more then C
i.e. Salary of B is 120 and Salary of A is more then 25% of B.
Therefore Salary of A is Salary of B + 25% of Salary of B
i.e. Salary of A is 120 + 25% of 120 = 150.
And Salary of C is 100(as assumed).
Therefore Salary of A is 50%

If A's income is 25% more than B's income and B's income 20% more than...
Given Information:
- A's income is 25% more than B's income.
- B's income is 20% more than C's income.
To Find:
By what percent A's income is more than C's income.
Assumptions:
- Let's assume C's income as "x" units.
Calculating B's Income:
- B's income is 20% more than C's income, so B's income will be C's income plus 20% of C's income.
- B's income = x + (20/100)x = x(1 + 0.2) = x(1.2)
Calculating A's Income:
- A's income is 25% more than B's income, so A's income will be B's income plus 25% of B's income.
- A's income = x(1.2) + (25/100)(x(1.2)) = x(1.2)(1 + 0.25) = x(1.2)(1.25) = x(1.5)
Calculating the Percent Increase:
- To find the percent increase, we need to compare the difference between A's income and C's income with C's income.
- The difference between A's income and C's income is A's income minus C's income.
- Difference = x(1.5) - x = 0.5x
- Now, we divide the difference by C's income and multiply by 100 to get the percentage.
- Percent increase = (0.5x / x) * 100 = 50%
Answer:
A's income is 50% more than C's income.
- A's income is 25% more than B's income.
- B's income is 20% more than C's income.
