Applications and selections at three centres. Centre X: applied 400, selected 60. Centre Y: applied 250, selected 50. Centre Z: applied 350, selected 42. Which centre had the highest selection rate?

Selection rate = (selected ÷ applied) × 100. Centre X: (60 ÷ 400) × 100 = 15 percent, Centre Y: (50 ÷ 250) × 100 = 20 percent, Centre Z: (42 ÷ 350) × 100 = 12 percent. Centre Y has the highest rate, although Centre X selected the largest number of people.
