Let the cost price of the article be Rs. ‘2x’
So, marked price of the article = 2x × 1.6 = Rs. ‘3.2x’
Selling price of the article = 3.2x × 0.75 = Rs. ‘2.4x’
Profit = 2.4x – 2x = Rs. ‘0.4x’
ATQ;
0.4x = 45
Or, x = 112.5
So, marked price of the article = 112.5 × 3.2 = Rs. 360
Selling price of the article = 112.5 × 2.4 = Rs. 270
Required difference = 360 – 270 = Rs. 90
