It can be one of six numbers: 724, 643, 562, 427, 346, 265

452, 894. None other that I can think of
Look at the digit in tens place. If it is 5 or greater, round the digit in hundreds place to the next higher digit. If the digit in tens place is less than 5, leave the digit in hundreds place as it is. Change all the numbers to the right of the hundreds place to zeros. 261 rounded to the nearest hundred is 300.

Note: The first answer, above the line, can't be a solution, because it violaes the condition that its "... hundreds digit and ones digit is the same ..." .
