Noah
and Emzara had three children : Ham, Japheth and Shem.
The difference between
the parents' ages was the same as between Ham and Japheth
and between
Japheth and Shem.
Multiplying Ham and
Japheth 's ages equalled Noah's age.
Multiplying Japheth and
Shem's ages equalled Emzara's age.
The combined ages of all
five people amounted to ninety years.
