Answer 1

53]

The least fuel economic model is F326 as it has the lowest miles per gallon.

Number of litres required to cover 200 miles = (200 / miles per gallon) * liters per gallon

Number of litres required to cover 200 miles = (200 / 27) * 4.55 = 33.70 liters

Number of times to refill engine = Number of litres required to cover 200 miles / engine size

Number of times to refill engine = 33.70 / 2 = 16.85 times.

The answer is C

Additional price to be paid for G02F = £22,000 - £20,968 = £1,032

Fuel savings with G02F per year = [(miles per year / miles per gallon of F326) - (miles per year / miles per gallon of G02F)] * fuel cost per gallon

Fuel savings with G02F per year = [(10,000 / 27) - (10,000 / 32)] * £4.75

Fuel savings with G02F per year = £274.88

Number of years to drive for G02F to be more economical =  Additional price to be paid for G02F / Fuel savings with G02F per year

Number of years to drive for G02F to be more economical = £1,032 / £274.88

Number of years to drive for G02F to be more economical = 3.75 years

The answer is D
