ATQ, Let the cost price of 1000 grams of Sugar be Rs. 1000x. He gives 800 grams instead of 1000 grams. So, Selling price of 800 grams of Sugar = 1000x × 1.2 = Rs. 1200x Selling price of 1000 grams of Sugar = 1200x × (1000/800) = Rs. 1500x Required profit percentage = {(1500x – 1000x)/1000} × 100 = 50%
