Worked Solution & Example Answer:Study the population pyramids of France and India below and answer the questions that follow - NSC Mathematical Literacy - Question 4 - 2016 - Paper 2
Step 1
Approximately what percentage of France’s population fall in the category 30 – 35 years?
Answer
To determine the percentage of France’s population that falls within the 30 – 35 age category, we observe the population pyramid. The bar corresponding to ages 30-35 shows that approximately 8% of the population is in this age group. Thus, the answer is:
8%
Step 2
Compare and comment on the bases of each of the countries.
Answer
In comparing the population pyramids of France and India, we note the following:
-
France has a narrow base, indicating a low birth rate. This suggests a more stable population with fewer younger individuals. A narrow base is often associated with developed countries where family planning and access to education contribute to smaller family sizes.
-
India, on the other hand, has a broad base. This indicates a higher birth rate, which is typical of developing countries where larger families are more common due to cultural norms and lower access to contraceptives. The broad base suggests a young population that is likely to experience significant growth.
In summary, France’s narrow base signifies lower fertility rates whereas India’s broad base indicates higher fertility rates.
Step 3
She wants to use the scale to cut the dimensions on a piece of white material.
Answer
For the flags, Hanin used a scale of 1 : 23.
Given that the length of the flag on paper is 6 cm and the width is 3.9 cm, the actual dimensions can be calculated as follows:
- Actual length = 6 cm × 23 = 138 cm
- Actual width = 3.9 cm × 23 = 89.7 cm
To find the area of the flag:
- Area = Length × Width = 138 cm × 89.7 cm = 12,378.60 cm².
This confirms that the area of each flag, when completed, will indeed be 12,378.60 cm².
