Total doctors in hospital ‘A’ = 200  Male doctors in hospital ‘A’ = 200 × (75/100) = 150  Female doctors in hospital ‘A’ = 200 – 150 = 50    Total doctors in hospital ‘B’ = 200/2 = 100  Male doctors in hospital ‘B’ = 100 × (30/100) = 30  Female doctors in hospital ‘B’ = 100 – 30 = 70  Total doctors in hospital ‘C’ = 150 – 70 = 80  Female doctors in hospital ‘C’ = 30  Male doctors in hospital ‘C’ = 80 – 30 = 50  Female doctors in hospital ‘D’ = 120  Total number of doctors in all hospitals = 120 × (100/20) = 600  Total doctors in hospital ‘D’ = (600 - 200 - 100 - 80) = 220 Total number of male doctors in hospital 'D' = 220 - 120 = 100 Required % = [(50 - 30)/30] × 100 = 66.67%
