If the selling price of a product is multiplied by 2, then the resultant profit is 6 times the original profit. What is the original profit percentage?
Answer & explanation
Correct answer: option 1
Let the CP and SP of the article be Rs. x and Rs. y respectively, then
2y - x = 6 (y - x)
2y - x = 6y - 6x
6x - x = 6y - 2y
5x = 4y
x : y = 4 : 5
Now, we can say
CP of the article = Rs. 4
SP of the article = Rs. 5
Profit = 5 - 4 = 1
Profit percentage = \(\frac{1}{4}\) × 100 = 25%
