On one side of a weighing balance, Jenny has accidentally placed a magnet of 30 grams. On this side, she places items and on the other side, she places weight of 1 kg. Assuming that she sells items at cost price, how much profit or loss will she make on selling 1 kg of item?
Solution
Correct Answer: Option C
Due to magnet, she will give 970 grams of items but will take price for 1 kg. Her profit will be price of 30 grams item and selling price will be price of 1 kg grams of items.
profit = 30 grams
We know, profit percentage = (profit/Cost Price) × 100 = (30/970) × 100 = 3.09%
