A shirt was sold for Tk. 171 and the gain was as much percent as it costs in Taka amount. What was the purchase price of the shirt? Correct Answer None of these
Let, the purchase price is x So, ( 171 - x) /x × 100% = x% ( 17100 - 100x) /x = x 17100 - 100x = x2 x2 + 100x - 17100 = 0 x = - 190, 90 So, x value is 90 The purchase price was 90 Tk.
