Question

For selling an article for Rs 24, the profit% is equal to the cost price in rupees. Find the cost price of the article,​

Answer 1

Answer:

Rs.20

Step-by-step explanation:

Let the profit % be x.

Cost Price (CP) = x

Selling Price (SP) = Rs.24

Profit = SP - CP = 24 - x

Profit % = Profit/CP × 100

=> x = (24-x) / x × 100

=> x² = 2400 - 100x

=> x²+100x-2400 = 0

=> x²+120x-20x-2400 = 0

=> x(x+120)-20(x+120) = 0

=> (x-20)(x+120) = 0

=> x = 20 [Neglecting negative value of x]

Hence, the cost price of the article is Rs.20.
