A shopkeeper sells an article at 20% profit. If bought at 20% less and sold for Rs. 10 less, gain would be 25%. Find CP.
Correct Answer: Option A
Explanation:
CP = x, SP = 1.2x. New CP = 0.8x, new SP = 1.2x - 10. New SP = 1.25×0.8x = x. So 1.2x - 10 = x → 0.2x = 10 → x = 50.
CP = x, SP = 1.2x. New CP = 0.8x, new SP = 1.2x - 10. New SP = 1.25×0.8x = x. So 1.2x - 10 = x → 0.2x = 10 → x = 50.
