Study the Pie-chart and the table and then answer the questions.
The ratio of number of females in the areas S2 in the areas S5 is
Solution
Total population = 72 lakh Now Population of S2 = (135/360)*72 =27lakh Now females in S2 =Â $$\frac{1}{5}\times\ 27\ =5.4\ lakh$$ Now population of S5 = (60/360)*72 =12 Female in S5 =$$\frac{7}{20}\times\ 12$$ =4.2 lakh Now taking ratio We get 5.4:4.2 =9:7
