Answer 2

Let the cost price be 'x'.

Given that selling price of an article = 96.

Given that profit% = x%

We know that Cost price = [(100)/100 + Gain] * SP

⇒ x = [100/100 + x] * 96

⇒ x^2 + 100x = 9600

⇒ x^2 + 100x - 9600 = 0

⇒ x^2 + 160x - 60x - 9600 = 0

⇒ x(x + 160) - 60(x + 160) = 0

⇒ (x - 60)(x + 160) = 0

⇒ x = 60,-160{neglect negative value}

⇒ x = 60.

Therefore, Cost price of an article = 60.
