Answer 1

Answer:

55 is the answer

Step-by-step explanation:

may be 55

Answer 2

Answer:-

• The sum of the digits of the two digit number (x + y) is 5.

Solution:-

Let:-

• The digit in the tenth place be y.
• The digit in the one's place be x.

Then:-

Original number is 10y + x.

According to Question:-

On reversing the digit the number is 10x + y.

Now:-

We can solve the equation easily

=> 10y + x + 10x + y = 55

=> 11y + 11x = 55...........(i)

Now divide the equation (i) by 11

=> 11y + 11x = 55

=> 11y/11 + 11x/11 = 55/11

=> y + x = 5

Therefore:-

The sum of the digits of the two digit number (x + y) is 5.
