Question

If the sum of two digit Number and number obtained reversing the digit is 55,find the sum of the digit of the 2 -digit numbers

Answer 1

Answer:

2+3=5.

Step-by-step explanation:

sum of 2 digit number &number obtained reversing the digit =55,

now,

23+32=55.

hence,

2+3=5

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.
