Let original CP of the article was X. First Case: SP = X + 5% of X = 105X/100 Second Case: He bought article at 5% less. CP = X - 5% of x = 95X/100 SP = (105X/100) - 1 Gain 10%. SP - CP = Gain (105X/100) - 1 - 95X/100 = 10% of 95X/100 10X/100 -1 = 95X/1000 0.1X - 1 = 0.095X 0.005 X = 1 X = 200 So, Original CP was Rs. 200
