Question

the sum of a two digit number and the number formed by reversing the digits is always divisible by​

Answer 1

Answer: Answer is 11

Step-by-step explanation:

let the original number be 10x + y

then the number obtained by reversing the digit will be

10y + x

now applying the condition ;

sum of the two number = (10x + y ) + (10y + x)

= 11x + 11y

= 11(x + y)

which is always divisible by 11
