Question 1

A UK embassy buys supplies in Japanese yen. The total is ¥892,500. If the exchange rate is £1 = ¥185, what is the sterling cost?

Accepted Answer

£4,825

Answer

Sterling cost = ¥892,500 / 185 = £4,824.32, approximately £4,825.

Question 2

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?

Accepted Answer

£18,291

Answer

Cost = 12,800 x £1.429 = £18,291.20. Converting 142.9p to pounds gives £1.429, then multiply by the volume in litres.

Question 3

A civil servant flies from London to Washington DC (5,900 km) and claims a flat rate of £125 per 1,000 km. How much is the flight allowance?

Accepted Answer

£737.50

Answer

Number of 1,000 km units = 5,900 / 1,000 = 5.9. Allowance = 5.9 x £125 = £737.50.

Question 4

An office thermostat is set to 21 degrees Celsius. Using the formula F = (C x 9/5) + 32, what is this temperature in Fahrenheit?

Accepted Answer

69.8°F

Answer

F = (21 x 9/5) + 32 = (21 x 1.8) + 32 = 37.8 + 32 = 69.8°F.

Question 5

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?

Accepted Answer

Overspent by £46,667

Answer

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.
