In each of the following numbers, what should be the missing digit in the indicated place such that the number is a multiple of 11?

Answer»

8



Divisibility of 11: If the difference of the sum of the DIGITS at ODD places and the sum of the digits at EVEN places of a number is zero or a multiple of 11, then that number is divisible by 11.

As per divisibility rule of 11, difference = (x + 21) - 18 = x + 3

=> x + 3 = 11 => x = 8
