Answer:
1029
Step-by-step explanation:
This is a puzzle problem.
The key here is to recognize the first number given as a CLOCK TIME.
"355" -- make it look like a time, which is
3:55
How do we say this in English?
5 minutes to being 4, right?
or
5 to 4...?
So, it corresponds to "524".
Now, 2nd example:
1235 means 12:35
How do we say that in English?
It is 25 minutes to 1, so we say:
25 to 1, or "2521"
Get it?
Similarly, "850" would be:
8:50 which will mean
10 minutes to 9
or 10 to 9, which is:
"1029"
The answer would be 1029
