Question

If an item is sold at a profit percentage equal to the purchase price, then the selling price is Rs. 144, then the purchase price is indicated.​

Answer 1

Answer:

Let cp be x

Gain percent=x%

SP=Rs 144

$x = \frac{100}{100 + x\%} \times 144 \\ x = \frac{14400}{100 + x} \\ 100x + {x}^{2} = 14400 \\ {x}^{2} + 100x + 14400 = 0$
