5kg bag of sweets split into bags of 250g. Convert 5kg to grams which equals 5000By dividing the weight of each bag you can figure out how many bags she can make are 20 bags as 5000/250 = 20. She sells each bag for 65p therefore, she makes 1300p or £13 as 65*20 = 1300To work out percentage profit you must divide profit which is £13 by the initial cost which is £10 and multiple the answer by a hundred to convert the answer into a percentage therefore, (13/10)*100 = 130However, as the question specifies the percentage increase you must subtract the initial percentage which is a 100% from the profit percentage; 130-100 = 30. Therefore the final answer is 30%
