I am two digit no above 50 . the sum of my digits is 12. And the difference of my digits is 4 .who am I
What two numbers add up to 12? Which of those has a difference of 4?
my answer is 84
To find the two-digit number that meets the given conditions, let's break down the problem step by step:
Step 1: Determine the possible values for the tens digit.
Since the number is greater than 50, the tens digit can only be 6, 7, 8, or 9 (as 5 is not above 50).
Step 2: Determine the possible values for the ones digit.
The ones digit can be found by subtracting the tens digit from 12, as the sum of the digits is 12. So, the possible values for the ones digit are 12 - 6 = 6, 12 - 7 = 5, 12 - 8 = 4, and 12 - 9 = 3.
Step 3: Calculate the difference between the tens and ones digits.
We are given that the difference between the digits is 4. By checking the possible combinations, we find that only the number 86 satisfies this condition (8 - 6 = 2).
Therefore, the two-digit number above 50 with a digit sum of 12 and a digit difference of 4 is 86.
