The key steps are to convert the fractional ratio into a whole number ratio, calculate each person's share under both the correct and incorrect distributions, and then find the difference (gain or loss) for each person.
So, CP = 160. - Now, let's find the labelled price L using the sales information. - 8 toys were sold at a 20% discount on L. SP for these 8 toys = 8 (L (1 - 0.20)) = 8 (0.8L) = 6.4L. - The remaining 4 toys were sold at an additional 25% discount on the discounted price. The first discounted price was 0.8L. The second discount is 25% on 0.8L. SP for 4 (0.6L) = 2.4L. - The total selling price is the sum of the SPs of the two groups of toys. - Total SP = 6.4L + 2.4L = 8.8L. - We know the total SP is 2112. - 8.8L = 2112 - L = 2112 / 8.8 = 21120 / 88 = 240. - The labelled price of one toy is Rs. 240. - The cost price of one toy is Rs. 160. - The question asks for the profit percentage if no discounts were given. - If no discounts were given, the selling price of each toy would be the labelled price L = 240. - Profit per toy = SP - CP = 240 - 160 = 80. - Profit percentage = (Profit / CP) 100 = (80 / 160) 100 = (1/2) 100 = 50%. 37. Instead of dividing Rs. 117 among X, Y and Z in the ratio 1/2 : 1/3 : 1/4, by mistake it was divided in the ratio of 2 : 3 : 4. Who gains the most benefit and by how much?
