Detailed Solution
Download Solution PDFPercentage of females in factory A and C together (above 40 years) = 60%
Percentage of males in factory A and C together (above 40 years) = 40%
Number of males in factory A and C together (above 40 years) = 40/100 × (50 + 110) = 64
Percentage of females in factory B and D together (above 40 years) = 50%
Percentage of males in factory B and D together (above 40 years) = 50%
Number of males in factory B and D together (above 40 years) = 50/100 × (70 + 120) = 95
∴ required ratio = 64 : 95
