Question

The tens and units digits of a number are the same. when a number is added to its reverse the sum is 110.what is the number?....plz give correct answer

Answer 1

Answer:

55

Step-by-step explanation:

Let, 'x' be the tens digit and 'y' be the ones digit.

Then, number will be '10x +y'

on reversing number will be '10y + x'

It is given that both the digits are equal

It means. x=y

According to question...

10x + y +10y+x = 110

11x + 11y = 110

x+y= 10

.. x + x= 10. (x=y)

x= 5

So,. y= 5

Hence, number is 55
