My tens digit is double the ones digit,Iam less than 50 and greater than 40...What number am I?

Which of these numbers fits?

41, 42, 43, 44, 45, 46, 47, 48, 49

i am greater than 30 and less than 40. the sum of my digits is less than 5.

To find the number that satisfies the given conditions, we can break down the information given.

The tens digit is double the ones digit. Let's represent the ones digit as 'x'. So, the tens digit would be '2x'.

The number is less than 50 and greater than 40. This means that the tens digit can only be 4, and the ones digit can be any number from 0 to 4.

By substituting the value of the tens digit (4) into our equation for the ones digit (2x), we can solve for 'x':

2x = 4
Dividing both sides of the equation by 2:
x = 2

So, the ones digit is 2, and the tens digit is 4. Therefore, the number that meets all the given conditions is 42.
