Question
What is respective ratio of the number of males in
Dehradun and females in Lucknow together to the number of males in Pune and females in Chandigarh together?Solution
Number of males in Dehradun = 16% of 65% of 24500 = 2548 Number of females in Lucknow = 24500 of 24% of 45% = 2646 Therefore, Total = 2548 + 2646 = 5194 Number of males in Pune = 18% of 70% of 24500 = 3087 Number of females in Chandigarh = 4116 Total = 3087 + 4116 = 7203 Therefore, Required ratio = 5194 : 7203 = 106 : 147
