Question 948771: I am a two digit odd number between 30 and 100. My tens digit is the double of the ones digit. What am I? Answer by Fombitz(32388) (Show Source):
You can put this solution on YOUR website! Look at the odd numbers 1,3,5.
Double them to get the tens digit.
2,6,10.
Knock out the 10, too large, greater than 100.
Knock out the 2, too small, less than 30.
Leaves you with 6.
