Question

Selling an article for Rs. 144 gives the same percentage of profit as its purchase price. What will be the purchase price of the article?

Answer 1

Answer:

72 is the percentage of profit

Answer 2

Answer:

Rs.80

Step-by-step explanation:

Let's say C.P. = x

Now, profit = x% (Given)

So, x + x% of x = 144

=> x + x²/100 = 144

=> x² +100x -14400 = 0

=> x² + 180x - 80x - 14400 =0

=> (x+180)(x-80) = 0

=> x= 80
