Question
Difference between selling price of certain number of
items, when sold at Rs. 16 per item instead of Rs. 12 per item is Rs. 128. Total cost price of these items is Rs. 256. If the items are sold at a profit of 35%, then find the total selling price of 25 such items.Solution
Let, number of items sold be ‘x’.
ATQ, 16 × x – 12 × x = 128
Or, 4x = 128
So, x = (128/4) = 32
Cos price of each item = (256/32) = Rs. 8
Selling price of an item when sold at a profit of 35% = 1.35 × 8 = Rs. 10.8
So, the total selling price of 25 items sold at 35% profit = 25 × 10.8 = Rs. 270
