Pie Chart Percentages (Year 6) | CGP Plus - Free Printable

Let's solve each part of the problem step by step using the information provided in the pie chart and the survey details.

---

Given:

- Total number of customers surveyed = 200
- Pie chart shows percentages for each topping:
- Don’t like chips: 5%
- Salt and vinegar: 20%
- Ketchup: 16%
- Mayonnaise: 4%
- Curry sauce: 23%
- Gravy: 11%
- Cheese: 21%

---

## 1. Complete the table

We need to fill in:
- Percentage (already given)
- Number of customers = (Percentage / 100) × 200

Let’s calculate:

| Topping | Percentage | Number of Customers |
|-------------------|------------|----------------------|
| Don’t like chips | 5% | 10 (given) |
| Salt and vinegar | 20% | (20/100) × 200 = 40 |
| Ketchup | 16% | (16/100) × 200 = 32 |
| Mayonnaise | 4% | (4/100) × 200 = 8 |
| Curry sauce | 23% | (23/100) × 200 = 46 |
| Gravy | 11% | (11/100) × 200 = 22 |
| Cheese | 21% | (21/100) × 200 = 42 |

✔ Completed Table:

| Topping | Don’t like chips | Salt and vinegar | Ketchup | Mayonnaise | Curry sauce | Gravy | Cheese |
|-------------------|------------------|------------------|---------|------------|-------------|--------|--------|
| Percentage | 5% | 20% | 16% | 4% | 23% | 11% | 21% |
| Number of Customers | 10 | 40 | 32 | 8 | 46 | 22 | 42 |

## 2. How many customers chose either cheese or ketchup?

Cheese: 42
Ketchup: 32
Total = 42 + 32 = 74 customers

✔ Answer: 74 customers

---

## 3. How many more customers chose curry sauce than salt and vinegar?

Curry sauce: 46
Salt and vinegar: 40
Difference = 46 − 40 = 6 customers

✔ Answer: 6 more customers

---

## 4. Do more customers prefer curry sauce and gravy, or salt and vinegar and ketchup?

First, calculate totals:

- Curry sauce + Gravy = 46 + 22 = 68
- Salt and vinegar + Ketchup = 40 + 32 = 72

Compare: 72 > 68

✔ Answer: More customers prefer salt and vinegar and ketchup.

## 5. The manager decided that the customers who don't like chips should choose their favourite topping anyway. 4 people chose cheese and 6 chose ketchup. What percentage now prefer ketchup?

Originally:
- Don’t like chips = 10 people
- These 10 are now reclassified into toppings.
- 4 → cheese
- 6 → ketchup

So we add 6 to ketchup.

Original ketchup count = 32
New ketchup count = 32 + 6 = 38

Now total number of customers is still 200 (same group, just reclassified).

New percentage for ketchup =
$$
\frac{38}{200} \times 100 = 19\%
$$

✔ Answer: 19% now prefer ketchup

✔ Final Answers:

1. Table completed as shown above.
2. 74 customers chose cheese or ketchup.
3. 6 more customers chose curry sauce than salt and vinegar.
4. More customers prefer salt and vinegar and ketchup.
5. 19% now prefer ketchup.
