SET 40, Q1. Correct Answer: E
We need to calculate the total amount of fat consumed and then calculate the daily consumption.
We need to work out the total amount of fat consumed, which is the amount per person (both saturated and unsaturated), multiplied by the number of people. This gives: (2.44 + 2.19) × 60120 = 278356 This is now in kg/year and we want the daily rate, so we divide by 365 days/year: 278356 / 365 = 762.6 kg/day
You must be careful at this point not to think you have finished the question and mark option B as the correct answer, because you still have to correct the order of magnitude. The population is in thousands so we need to multiply by 1000, giving us 762600 kg per day. The answer options expressed in kg are much lower figures than this, but if we divide by 1000, to convert kg to tonnes, we get 762.6 tonnes, which is option E.
