5 --------- 5
10 ---------- 6
11 ---------- 7
12 ---------- 8

if we consider no from 1 to 10 then out of all these no. only one no . that is 5 which is when converted in decimal gives 30 , which is divided by 10
another if we take no from 11 to 20 then no 14 gives correct ans and hence this is applicabe in fruther cases
hence if we take probability of such solution then it will be 1/10

It does not matters which base we are converting to decimal.
When we convert it to decimal the last digit will be any from 0 - 9 ,
i.e. 0,1,2,3,4,5,6,7,8,9
Since we need to find out whether the converted decimal is divisible by 10 the last digit needs to be zero (0).
So total outcomes = 10
i.e. (0,1,2,3,4,5,6,7,8,9)
Favourable outcome = 1
i.e. any number ending with zero
So probability will be: 1/10.
Simple
