Question

In number 314* replace * by a digit so that the number formed is divisible by 11

Answer 1

Answer:

Divisibility rule of 11 is that the difference between the sum of the digits at the odd and even places equals 0 or divisible by 11, then the number is divisible by 11.

Now ,

Sum of digits at odd = 3 + 4 = 7

Sum of digits at even = 1 + ( * )

Now , according to rule

Sum of odd - sum of even = 0

7 - 1 - ( * ) = 0

( * ) = 6

Hence , 6 is the number that can replace *
