      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 = 600−120=480. Doctors above 50: 40% of male doctors = 0.4×480=192. 25% of female doctors = 0.25×120=30. Total doctors above 50: 192+30=222. So, 222 doctors are above the age of 50 in Hospital D.
