Question

The difference between a two digit number and the number obtained by reversing its digts is
18. What is the difference between the digits of the number?
​

Answer 1

Answer:

2

Step-by-step explanation:

Let the ten’s digit be m and one’s digit be n so that the number is 10m+n.

Then the reversed number is 10n+m

Given (10m+n)-(10n+m)=18

So 9m-9n=18

9(m-n)=18

m-n=2
