It is greater than 37,493. it is less than 37,503. it is an even number. the value of the mystery number rounded to the nearest ten is less than the mystery number. the value of the mystery number rounded to the nearest thousand is greater than the mystery number.

37493 < x < 37503

it is evenso choices so far are : 37494, 37496, 37498, 37,500, 37,502
