Question #1 – World Fossil Fuel Regulation Which mine can produce the greatest amount of units of electricity before it runs out of coal? 1. Folen 2. Dirme 2. Ilt 3. Ryken 4. All Others Quest... ion #2 – Newmellum Retail Outlets If all staff, both operations and admin, were required to wear trousers, shirts and shoes, how much would this cost the company? 1. £4,698 2. £12,843 3. £18,648 4. £27,364 5. £33,615In year 7, what will be the sales difference between the two companies, in millions, if X-Brade manages a 15% increase while SBRC manages only 7.5%? The correct answer is (E) - £181.88 In this question, you first need to calculate the sales of each company for Year 7, knowing each company sales in year 6. You are told that in year 6 X-Brade's sales are £69 million and SBRC's sales are £243 million. Let each company's sales in year 6 count as 100%. In year 7 SBRC's sales increased by 7.5%. To understand SBRC's sales' worth in year 7, relate to it's sales in year 6, which are given in the question, as 100%. This means that SBRC's sales value in year 7 is 100% + 7.5% = 107.5% of its sales value in year 6 (since they are 7.5% higher). In year 7, X-Brade's sales increased by 15%. To understand X-Brade's sales' worth in year 7, relate to it's sales in year 6, which are given in the question, as 100%. This means that X-Brade's sales value in year 7 is 100% + 15% = 115% of its sales value in year 6 (since they are 15% higher). To calculate a new value knowing the old value and the change percentage, use the formula: New Value = Old Value x (% of the New Value relatively to the Old Value/100%) *Notice! % of the Old value always equals 100% Therefore, in this question the sales for each company in year 7 will be calculated as follows: Sales in year 7 = Sales in year 6 x (% Sales in year 7 relatively to % Sales in year 6 /100%) *Notice! % Sales in year 6 = 100% Therefore, Sales in year 7 for SBRC = 243 x (107.5/100) = 243 x 1.075 = £261.23 Sales in year 7 for X-Brade = 69 x (115/100) = 243 x 1.15 = £79.35 The difference in sales between the two companies is: 261.23 - 79.35 = £181.88 (million) Another way to calculate a new value knowing an old value, would be relating to the old value as 100%, which in when translated to a raw number, equals 1 and therefore, New Value = Old Value x (1 + (% change/100)) Therefore, in this question the sales for each company in year 7 will be calculated as follows: Sales in Year 7 = Sales in Year 6 x (1 + (% change/100)) Therefore, Sales in year 7 for SBRC: 243 x (1 + (7.5/100)) = 243 x (1 + 0.075) = 243 x 1.075 = £261.23 Sales in year 7 for X-Brade: 69 x (1 + (15/100)) = 69 x (1 + 0.15) = 69 x 1.15 = £79.35The difference in sales between the two companies is: 261.23 ― 79.35 = £181.88 (million) [Show More]
