A person sells a TV set for Rs. 9400 and makes a certain loss. If he sells it for Rs. 10600, his profit is double the amount of his previous loss. What is the cost price of the TV?
A. Rs. 9600
B. Rs. 10000
C. Rs. 9800
D. Rs. 10200
Answer: Option C
Solution (By JKSSB Mock Tests)
Let Cost Price = x. Loss = x - 9400. Profit = 10600 - x. Profit = 2 * Loss. 10600 - x = 2 * (x - 9400). 10600 - x = 2x - 18800. 3x = 29400. x = 9800.
A dishonest dealer marks up his goods by 20% and gives a discount of 10%. Besides, he uses a faulty balance which reads 1 kg for 800g. What is his net profit percentage?
Explanation:
Let true CP of 1000g be 1000. He marks it at 1200 and sells at a 10% discount, making SP = 1080. But he gives only 800g. The actual CP for him is 800. Net Profit = 1080 - 800 = 280. Net Profit % = (280 / 800) * 100 = 35%.
