Question
Matthew sells Chocolates in the packs of 6 chocolates,
12 chocolates, 18 chocolates and 24 chocolates etc, but the rate is necessarily uniform. One day Carlos purchased at the rate of 6 chocolates for a rupee and the next day he purchased equal number of chocolates at the rate of 12 chocolates for a rupee. Next day he sold all the chocolates at the rate of 18 chocolates for Rs. 2. What is his percentage profit or loss?Solution
Cost of one chocolate (in first case) = 1/6 = 16.66 paise Cost Price of one Chocolate (in second case) = 1/12 = 8.33 paise Average Cost Price of one chocolate = ((16.66 + 8.33)/2) = 12.5 paise Selling Price of one chocolate = 200/18 paise Loss % = (12.5- 200/18 )/12.5 ×100 = 25/(18 ×12.5) ×100 = 11.11%
47.87% of 749.76 + 35.11% of 399.76 = √? + 23.15 × 20.87
