Question

The sum of the digit of two digit number is 12.If digit are interchanged and resuiting number is added to original number we get 132

Answer 1

Let us assume, x and y are the two digit of the two-digit number

Therefore, the two-digit number = 10x + y and reversed number  = 10y + x

Given:

x + y = 12 ----------------1

also given:

10x + y + 10y + x = 132
11x + 11y = 132
x + y = 12 -------------2

There is some problem in this....we can not solve this as both the equations are same.
