In hospitalĀ D, 40% of the male doctors and 25% of the
female doctors are above the age of 50. Find the total number of doctors above the age of 50 in hospitalĀ D. Read the following information carefully and answer the questions: Ā Ā In hospital āAā, total number of doctors is 200, out of this 75% are male doctors and rest is female doctors. In hospital āBā total number of doctors are half of the doctors of hospital āAā. In hospital āBā, 30% is male doctors. Total number of doctors in hospital āCā is 70 less than the number of male doctors in hospital āAā. In hospital āCā, female doctors are equal to the male doctors of hospital āBā. In hospital āDā, total female doctors are 120, which 20% of total doctors.Solution
Find total doctors in Hospital D: Female doctors are 20% of total doctors. Total doctors = 120/0.2 =600. Find male doctors in Hospital D: Male doctors = 600ā120=480. Doctors above 50: 40% of male doctors = 0.4Ć480=192. 25% of female doctors = 0.25Ć120=30. Total doctors above 50: 192+30=222. So, 222 doctors are above the age of 50 in Hospital D.
