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
