If goods are purchased for Rs. 840 and one-fourth of them are sold at a loss of 20%, at what profit percentage should the remainder be sold to gain 20% on the whole transaction?
A. 30%
B. 28.33%
C. 35%
D. 33.33%
Answer: Option D
Solution (By JKSSB Mock Tests)
Total Cost Price = 840. Target Selling Price = 840 * 1.20 = 1008. Cost Price of one-fourth = 210. Selling Price of this part = 210 * 0.80 = 168. Remaining Selling Price needed = 1008 - 168 = 840. Cost Price of remainder = 630. Profit required on remainder = 840 - 630 = 210. Profit percentage = (210 / 630) * 100 = 33.33%.
