My tens digit is double the ones digit i am less then 50 greater than 40 It has to be a number between 41-49 because its greater then 40 but less than 50 so both numbers are canceled out. if the tens digit must be a 4 divide it by 2 you get 2 2 doubled is 4. 42 :]

Let us solve this by algebra. Now, let's realize that any two digit number can be represented in the form of 10*x + y. x here is the ten's digit and y here is the one's digit. Therefore, according to the question, x = 2y. Therefore 10x + y becomes 21y Now, since the number is between 40 and 50, and 21 * 2 = 42 therefore, y = 2 and hence x = 4 and therefore the number is 42

I also got 42.

That means that the 10s digit is 4. So the ones is 1/2 of 4 or 2. 42
