20. The table gives some information about the nutritional value of 1000 grams of a breakfast cereal.
| Every 1000 g contains: | |
|---|---|
| Fat of which saturated fat | 65 g 40 g |
| Protein | 80 g |
| Salt | 2 g |
(a)
Show that
saturated fat : other fat = 8 : 5 [2]
(b) How much salt is there in a 50 gram serving of this cereal? [3]
(c)
It is recommended that an adult eats no more than 6 grams of salt per day.
Meena is an adult and eats a 50 gram portion of the cereal.
What fraction of her daily salt intake does Meena eat?
Give your answer as a fraction in its simplest form. [2]

| (other fat = ) 65 – 40 = 25 | B1 | |
| 40 : 25 (leading to 8 : 5) | B1 | Allow 40g : 25g |

| \(\dfrac{2}{1000} \times 50\) or equivalent | M2 | May be in steps e.g. 1000 ÷ 50 = 20, 2 ÷ 20 or 100g is 0.2 g of salt, 50g is 0.1g of salt M1 for \(\dfrac{2}{1000}\) or \(\dfrac{50}{1000}\) or 2 × 50 or 1000 ÷ 50 = 20 (servings) seen |

| \(\dfrac{1}{60}\) | A1 | FT ‘their 0.1’ provided ‘their 0.1’ is a decimal with at least one decimal place |
