Members of a certain group of airline pilots fly only Boeing and Airbus airplanes. A total of 25 of the pilots fly Boeing airplanes, and 75 of the pilots fly Airbus airplanes.
In the table, select two numbers that are consistent with the information given. In the first column, select the row that displays the largest number of pilots in the group who fly either Boeing or Airbus airplanes. In the second column, select the row that displays the largest number of pilots in the group who possibly could be flying both Boeing and Airbus airplanes. Select only one option in each column.
As per the given data in the stimulus,
MAX possible number of pilots in the group who fly either Boeing or Airbus airplanes = 75 + 25 = 100 (with no pilot as flying both)
MIN possible number of pilots in the group who fly either Boeing or Airbus airplanes = 75 + 25 - 25= 75 (with 25 pilots as flying both)
ie, 75 <= (Either) <=100
MAX possible number of pilots in the group who possibly could be flying both Boeing and Airbus airplanes = 25
MIN possible number of pilots in the group who possibly could be flying both Boeing and Airbus airplanes = 0
ie, 0 <= (Both) <= 25
Only figures 90 and 10 satisfy both the criteria
(Possible for Boeing = 25, Airbus = 75 and Both = 10;
so, Either Boeing or Airbus = 25 + 75 - 10 = 90)
So,
Fly either Boeing or Airbus = 90
Fly both Boeing and Airbus = 10
