Question
A shopkeeper sells an article for 10% profit. If he buys
it for 4% less and sells it for profit then he gets Rs. 10 more. What is the original cost price?Solution
C.P1 = 100, S.P1 = 110 C.P2 = 96 S.P2 = [(100 + 18(3/4)/100] × 96 = 144 If diff. = 4 then C.P = 100 If diff = 100 then C.P = (100 × 10)/4 = 250
