Question 87

If R019 is divisible by 11, find the value of the smallest natural number R?

Solution

Divisibility rule of 11 is:

sum of digits in odd place should be equal to sum of digits in even place or their differences should be divisible by 11.

here, $$R+1=0+9=9$$.

So, the smallest digit should be 8 .

So,$$R= 8$$.

D is correct choice.
