Question 63

The given Bar Graph presents the percentages of population in the age groups, X(above 50 years), Y(20 to 50 years), Z(below 20 years)in five different villages, A, B, C, D and E with total population of 5000, 6000, 8000, 4500 and 6000 respectively.

What is the total number of persons in the age group of 20 to 50 years in the villages A and B, taken together?

Solution

Number of persons in the age group of 20 to 50 years in the village A$$=\frac{40}{100}\times5000=2000$$

Number of persons in the age group of 20 to 50 years in the village B$$=\frac{35}{100}\times6000=2100$$

$$\therefore\ $$Total number of persons in the age group of 20 to 50 years in both the Villages A and B$$=2000+2100=4100$$

Hence, the correct answer is Option D
