P4 General Studies: The Food Pyramid (Paper 3 (challenge))
Paper three mixes calculation with judgement: working bowls back from an energy share, how far a soft drink or fat intake passes the limit, label conversion, and why one item cannot settle the question.
Direct answers When a question asks how many percentage points over, work out the actual percentage first and then subtract; do not subtract the two energy figures.

02 Questions (10 items)
- FoundationHow should servings be adjusted for someone with higher energy needs?
- FoundationWhy is wholemeal bread preferred over white bread in the pyramid?
- FoundationWhy eat whole fruit rather than drink only juice?
- IntermediateA food has 12 g of sugar per 100 g. How much sugar is in a 50 g portion?
- IntermediateWhy is the sugar in one item not enough to judge whether the limit is exceeded?
- IntermediateWhen activity rises, which level may be increased moderately?
- ChallengeAt 2 400 kcal a day with grains at fifty five per cent, and 220 kcal per bowl, about how many bowls are needed?
- ChallengeA can of soft drink holds 39 g of sugar against a 25 g daily added sugar limit. By how many grams is it over?
- ChallengeFat supplies 700 kcal out of 2 000 kcal a day. How many percentage points above the thirty per cent limit is that?
- Error redoError clinic: the pyramid is arranged by the size of the food, so the upper levels must be solids. True?
03 Answers and one-line notes
| # | Answer | One-line note |
|---|---|---|
| 1 | Servings rise overall while the proportions between levels stay roughly the same. | Keeping the proportions and scaling the amounts up is what balanced eating means. |
| 2 | Wholemeal keeps the bran and germ, so it has more fibre and vitamins. | Refining removes most of the fibre. |
| 3 | Whole fruit keeps its fibre and makes the sugar easier to control. | A glass of juice may carry the sugar of two or three fruits. |
| 4 | 6.0 g | 12 times 50 divided by 100 gives 6.0 g. |
| 5 | You also need the whole day total against the daily limit. | One item may use only a small part of the limit; the daily total is what matters. |
| 6 | The grain level at the bottom. | Exercise uses energy and grains replace it most directly. |
| 7 | 6 bowls | 2 400 times 0.55 is 1 320 kcal, which divided by 220 gives 6 bowls. |
| 8 | 14 g | 39 minus 25 gives 14 g, so one can already passes the daily limit. |
| 9 | 5.0 percentage points | 700 over 2 000 gives 35.0 per cent, which is 5.0 points above 30. |
| 10 | No. | The pyramid is arranged by recommended servings, not by the size or state of the food. |
04 What to do after marking
- After marking, redo only the wrong items and write down which step went wrong (formula, unit, or misread number).
- Repeat the same item two days later; move to the next paper only when both attempts are correct.
- Parents only need the answer and note columns; there is no need to explain every item.
Paper four clears the conductor, insulator and battery direction misconceptions.Tutor Registration →
