A government fleet of vehicles uses 12,800 litres of diesel per month. Diesel costs 142.9p per litre. What is the monthly fuel cost to the nearest pound?
Answer: £18,291

An office thermostat is set to 21 degrees Celsius. Using the formula F = (C x 9/5) + 32, what is this temperature in Fahrenheit?
Answer: 69.8°F
F = (21 x 9/5) + 32 = (21 x 1.8) + 32 = 37.8 + 32 = 69.8°F.
A government project has a budget of £2.4 million allocated over 18 months. If 7 months have passed and £980,000 has been spent, is the project on budget based on a linear spend profile?
Answer: Overspent by £46,667
Monthly budget = £2,400,000 / 18 = £133,333.33. Expected spend after 7 months = 7 x £133,333.33 = £933,333. Actual spend = £980,000. The project is overspent by £980,000 minus £933,333 = £46,667.
A department is comparing two suppliers. Supplier A charges €18,500 (exchange rate £1 = €1.16) and Supplier B charges £15,200. Which supplier is cheaper and by how much?
Answer: Supplier B is cheaper by £748
Supplier A in sterling = €18,500 / 1.16 = £15,948.28. Supplier B = £15,200. Supplier B is cheaper by £15,948 minus £15,200 = £748.
