Is it correct to say "understood question" as well as "understandable question"?
Someone wrote me it and I'm not sure if it is mistake or another variant.
The context is: " It is an understood sentence."

It is an understood sentence.
is certainly not idiomatic. without additional context I am not clear what the intended meaning is, but whatever it is there is almost surely a better way to say it.
As LawrenceC's answer explains, "understood" can mean "implied, but not stated" but "It is an understood sentence." would not be a natural way to describe a sentence that was implied but not explicitly said.
If the meaning is that someone was able to understand the sentence, that could be phrased as:
It was an understandable sentence
or perhaps
It was clear that the sentence could be understood.
"Understood can also mean "known, with reasons and explanations that are also known" as mentioned in the comment by AmirhoseinRiazi
The interaction of smell with memory is poorly understood
The effect of friction on motion is well-understood.
The circulation of the blood was not understood by the ancient Greeks.
This use does not seem to be what the question intends.
Understood means not only "was able to receive the meaning" but can also mean "not expressed, assumed."
It's been understood we don't talk to Mike (we didn't talk about not talking to Mike, we just assumed we should not and did not).
This is different from understandable which means "able to be interpreted or get the meaning."
I understood you didn't want me to talk to Mike (I told you this and you are acknowledging you know what I mean).
If you want to say "able to be interpreted or get the meaning" the word understandable is better.
