A: 88% of white pigeons return to lab = 88 / 100 * 25 = 16 pigeons. 80.5 % of gray pigeons return to lab = 250 * 80.5 / 100 = 192 pigeons. The total number of pigeons that returned to lab = 25 + 192 = 386 pigeons. The percent of total number of pigeons that returned to lab is 386 / 386 = 81%. The answer is (E).
