A 50-year-old biological father and a 49-year-old biological daughter would mean the father was 1 when she was born. That is impossible, so the teacher wrote “Read the problem carefully!” and treated 49 as wrong.People then invent extra assumptions the problem never states:There is more than one daughter, and their ages add up to 49 (twins of 24.5, or 27 and 22, or three daughters, etc.).
She is an adopted or step-daughter, so the 1-year gap is allowed.
The wording is a trick about “when the father was 50” rather than “the father is 50.”
None of those extra conditions appear in the text. They are after-the-fact patches for a badly written question.Bottom line
If you answer only what is written, the daughter is 49.
If the teacher wants a different number, the problem itself is defective, not the student’s arithmetic.
@jiro_3_ Family financing should be one of the basic things you have to talk about in a relationship.
So it doesn't bring up some other issues later on.
@7xjpf It becomes flaccid when you're exhausted, for like 3-4 hours, after resting for sometimes it becomes erect again like a mad dog looking for something to devour.
