If A is 25% more than B, the B is ? less than A.

A. 10%
B. 15%
C. 20%
D. 25%

A = (5/4)B

4A = 5B
B = (4/5)A
B = 80% of A

looks like B is 20% less than A

Thanks. That's what I thought.

To find the answer to this question, we need to understand what it means for A to be 25% more than B.

If A is 25% more than B, we can express it mathematically as:

A = B + (25/100) * B

Simplifying the equation, we have:

A = B + 0.25B
A = 1.25B

Now, let's find out how much B is less than A.

B is the "base" amount, and since A is 25% more than B, we can calculate the difference by subtracting B from A and finding the percentage difference:

Difference = (A - B) / A * 100

Plugging in A = 1.25B, we have:

Difference = (1.25B - B) / 1.25B * 100
Difference = (0.25B) / 1.25B * 100
Difference = 0.2 * 100
Difference = 20%

Therefore, B is 20% less than A, so the answer is C. 20%.
