<h2>Given :-</h2>
- In a two digit number the tens digit is one more in a two digit number the tens digit is one more than toys the unit digit the sum of the digits is 36 less than the number formed by reversing the digits find the product of the digit
- The Number
Let the digit at unit place be y.
Hence,
Tens = (2y + 1)
Now,
- 2y + 1 + y + 36 = 10y + 2y + 1
- 2y + y + 36 + 1 = 10y + 2y + 1
- 3y + 36 + 1 = 12y + 1
- 3y + 37 = 12y + 1
- 12y - 3y = 37 - 1
- 9y = 36
- y = 36/4
- y = 4
Now,
Ones formed = 2(4) - 1 = 9
