A person sells an article at 20% profit. If he had bought it at 20% less and sold it for Rs. 5 less, he would have gained 25%. Find CP.
ARs. 25
BRs. 50
CRs. 40
DRs. 60
✓ Correct Answer: A — Rs. 25
Let CP=100x, SP=120x. New CP=80x. New SP = 1.25*80x = 100x. 120x - 100x = 5 => 20x = 5 => x = 1/4. CP = 100 * (1/4) = 25.
