If rounded to the nearest 100, then any number between 150 and 250.
If rounded to the nearest 10, any between 195 and 205.
[For rounding fives, I round so that the last digit after rounding is even. This avoids the bias introduced when you always round up 5s or always round down 5s.]
199 If it's 200 rounded to nearest ten, then the number must be between 195 and 205. Only 199 has the correct digit sum.
200*200=400 200+200=400
The digit in the tens position is 7, so the number is rounded up to 200.
Three numbers that fit these criteria are:108, 144, and 180.
Any prime numbers of about 66 or 67 digits will do.
199 If it's 200 rounded to nearest ten, then the number must be between 195 and 205. Only 199 has the correct digit sum.
199
200*200=400 200+200=400
200
First part means that the number is between 150 and 200 Second part that it is between 195 and 200 as 1+9=10 then the number is 199
I am an even three digit number If you round me to the nearest ten I become 200 The sum of my digets is 18 What number am I?
199 if rounded to the nearest tens its 200 and rounded to the nearest hundred its 200. Alternately 0.199 for the same reason, it rounds to 0.2
The digit in the tens position is 7, so the number is rounded up to 200.

Oh, dude, that's an easy one! The smallest 3-digit number that can be rounded to 200 is 150. It's like rounding down to the nearest hundred, you know? So, 150 is the lucky winner in this scenario.
