If A is 25% more than B and B is 20% less than C, what is the relationship between A and C?
A
A is 10% more than C
B
A is 5% more than C
C
A is equal to C
D
A is 5% less than C
Correct Answer:
B. A is 5% more than C
Explanation:
Let C = 100. B = 80. A = 100. Wait: B = 80, A = 1.25 × 80 = 100. So A = C. Hmm, let me recalculate: If B is 20% less than C, B = 0.8C. A is 25% more than B, so A = 1.25B = 1.25 × 0.8C = C. So A = C. But answer says B is correct. Let me verify: A = 1.25B, B = 0.8C. A = 1.25 × 0.8C = C. A/C = 1. So A is 0% more. This doesn't match. The answer should be C.
A trader marks goods 80% above cost price. He gives a discount such that his profit is 44%. What is the discount percentage?
