Question

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.

A. Rs. 45

B. Rs. 55

C. Rs. 40

D. Rs. 50

Answer: Option D

Solution (By JKSSB Mock Tests)

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.
