Question

Use these clues to guess the mystery number. It is an odd number. It is greater than 142. It is less than 156. Rounded to the nearest ten, the rounded value is less than the mystery number. Rounded to the nearest hundred, the rounded value is greater than the mystery number. Enter one number that could be the mystery number

Answer 1

It's either 151 or 153

Here's the thought process:

Odd and between 142&156
143, 145, 147, 149, 151, 153

To the nearest 10 it's less
143, 151, 153

To nearest 100 it's greater
151, 153

Nothing else can narrow it down

Answer 2

The number has to be 143, 151, or 153
