Best ResponseYou've already chosen the best response.4well the mystery number assuming its an integer must be 143, 145, 147, 149 , 151, 153 or 155

Best ResponseYou've already chosen the best response.4now you need to check out the rounding

Best ResponseYou've already chosen the best response.4Hint 143 is rounded to nearest 10 is 140 (I'm not saying it is 143 but its a possibiilty)

Best ResponseYou've already chosen the best response.4151 and 153 rounded to the nearest 10 is 150 which is also less that these numbers.

Best ResponseYou've already chosen the best response.4 now you need to check the last condition  the number rounded to the nearest 100.

Best ResponseYou've already chosen the best response.1Odd numbers meeting the range criteria will be \[143,145,147,149,151,153,155\] For the mystery number rounded to the nearest \(10\) to be less than the mystery number, that means the units digit must be less than \(5\), or we would round it up: \[0\rightarrow0\]\[1\rightarrow 0\]\[2\rightarrow 0\]\[3\rightarrow 0\]\[4\rightarrow 0\]\[5\rightarrow 1\]\[6\rightarrow 1\]\[7\rightarrow 1\]\[8\rightarrow 1\]\[9\rightarrow 1\] That means our mystery number must end in an odd digit which rounds to \(0\), which leaves only \(1\) and \(3\) as possible last digits. For the mystery number rounded to the nearest \(100\) to be greater than the mystery number, it should be clear upon a bit of thinking that the 10s digit must be one from the table which rounds up rather than down. Combine that with your options for the final digit and you should have your two possible answers.

Best ResponseYou've already chosen the best response.1That was a bit unclear; I apologize. \(0\) in the right hand side of the table means "round down" and \(1\) means "round up".
