Study the following graph carefully and answer the given questions
The Pie chart shows the percentage of population in five different villages. Total population of all the villages are 26800.

1. Total population of village A and B is approximately what percentage more/less than the total population of village C?

Ans: 2
Population of village A= (26800 * 24)/100 = 6432
Population of village B= (26800* 16)/100 = 4288
Population of village C= (26800*28)/100 = 7504
Total Population of village A and B = 6432 + 4288 = 10720
Require percentage = [(10720 – 7504)/7504] * 100
= (3216/7504) * 100 = 42.85% ≈ 43%

 

2. If the ratio of the number of male and female in village B is 5:3 then approximately what percentage of male in village B is more/less than the total population of village D?

Ans: 1
Population of village B= (26800* 16)/100 = 4288
Population of village D= (26800* 12)/100 = 3216
Male in village B = (5/8) * 4288 = 2680
Require percentage (less) = [(3216 – 2680)/3216] * 100
= (536/3216) * 100 = 16.67% ≈ 17%

 

3. What is the ratio of population of village E and population of village B?

Ans: 3
Population of village B= (26800* 16)/100 = 4288
Population of village E= (26800* 20)/100 = 5360
Require ratio = 5360: 4288 = 335: 268

 

4. If 15% population of village E has electricity connection and 50% population of village C has electricity connection then what is the total number of people in village E and village C who does not have electricity connection?

Ans: 3
Population of village E= (26800* 20)/100 = 5360
Population of village C= (26800*28)/100 = 7504
Total number of people in village E who does not have electricity connection,
= (85 * 5360)/100
= 4556
Total number of people in village C who does not have electricity connection,
= (50 * 7504)/100
= 3752
Total number of people in village E and village C who does not have electricity connection,
= 4556 + 3752 = 8308

 

5. Population of village A and village D have how much more/less population than village B and village E?
