Question 60

If P713 is divisible by 11, find the value of the smallest natural number P?

Solution

Divisibility rule of 11 :

sum of digits in odd place should be equal to sum of digits in even place or their difference should be a multiple of 11.

here ,sum of digits in odd place is(P+1)

and sum of digits in even place is 3+7=10.

So, P would get minimum value only when

P+1=10 or, P=9.

D is correct choice.
