Replace in which with to which.
Delete her (and replace it with them if you like).
Because questions is plural, change answer to answers.
Since this example came from a source that’s more-or-less journalism (the AP Stylebook sometimes differs from The Chicago Manual of Style), you can keep 80% if you like, instead of replacing it with Eighty percent… as long as you rewrite that sentence so the numeral isn’t the first thing in it (because even AP says not to begin a sentence with a numeral).
Like so many “Psychology says” or “WTF fun fact” memes, this one contains much nonsense. (‘Oh, the majority of women say they have at least once in their lives asked a rhetorical question, so this proves that women always know the answer before they ask you something!’) I don’t have a specific number handy to quote at you, but you can rest assured that the majority of men also ask rhetorical questions sometimes.
Eighty percent of women ask questions to which they already know the answers. This is why it’s best to tell the truth.
(Now I have a Depeche Mode song running through my head…)
Good song. And, ppppth, 80%? Nah, women are always right. Right? Right? Yup, right.
So, anyway, according to this, 20% of women do not ask questions to which they already know the answer? Ever? Huh. 80% of the time women ask questions to which they… that’s weird, too. Really, shouldn’t the plan be to basically tell the truth anyway, regardless of the gender of the person asking the question? What’s the percentage of men who ask questions when they already know the answer? Is that related to mansplaining? If that is a writing prompt, it could prompt a lot of writing.
