How old was Joseph Cook when he died?

well it's hard to say but i reckon about 50-90.

Joseph Cook died on July 30, 1947 at the age of 86.

84 years, 10 months and 5 days old

70 years, 10 months and 26 days old

If you mean Jesus' father, Joseph, the Bible does not say. If you mean Jacob's son, Joseph, in Egypt, he died at the age of a hundred and ten(Genesis 50:26)
