N'oge a, James dị afọ iri na asatọ - isii = afọ iri na abụọ. N'ihi ya, nwanne James nke okenye dị afọ 12 + 4 = afọ 16. Azịza ya bụ: 16. <eng> John was 39 - 3 = 36 years old 3 years ago. So that means in 6 years James will be 36 / 2 = 18 years old. So right now James is 18 - 6 = 12 years old. So James's older brother is 12 + 4 = 16 years old. The answer: 16.
