The 'Healthy Options' shop serves a range of organic foods. The manager has employed a new assistant and has asked her to prepare 30kg of their 'nut and raisin' mix, which should consist of 30% peanuts, 20% hazelnuts and 50% raisins. The assistant has, however, made a mix using 10kg of each. The manager told her to add the minimum amount of extra ingredients to make the proportions right.What should be the mass of the final mix (to the nearest 1kg if necessary)?
Correct answer: A. 30kg
- A. 30kg
- B. 33kg
- C. 40kg
- D. 50kg
Explanation
The correct answer is Option A: 30kg. The assistant needs to add 10kg more of each nut and raisin to reach the desired mix composition of 30% peanuts, 20% hazelnuts, and 50% raisins. This brings the total mass of the final mix to 30kg. The other options do not accurately reflect the minimum additional amount needed to adjust the mix proportions.
