Hiya!
Yes, like the other answer, Zarina is ten and her father is forty. Yes, there are many possibilities as to what the ages could be because of those two variables, but 10×40 is 400, which is the only correct answer. Her father can't be ten and she forty, that doesn't make sense! They both cannot be 25, either, because that does not multiply to 400.
I hope that this is a good explanation! :)
If you found this especially helpful, I'd appreciate if you'd vote me Brainliest for your answer, if other people did not provide a helpful answer (but, I'm sure they did!). I want to be able to assist more users one-on-one! :)
