Given:
In a two digit number the tens digit is 6 more than the units digit.
If the digits are interchanged, the sum of the new and the original number is 132.
To find:
The original number.
Solution:
Let the unit digit of the original number be x. So, the tens digit is (x+6) and the value of the number is:
If we interchange the digits, then the value of new number is:
The sum of the new and the original number is 132.
Divide both sides by 22.
So, the unit digit of the original number is 3 and the tens digit is:
Therefore, the original number is 39.
