Question

replace * in the number 64*719 by the smallest , so that it is divisible by 11​

Answer 1

Answer: 2

Step-by-step explanation:

if a number is divisible by 11, then the difference between the sum of alternate digit is either 0 or a multiple of 11

Let x be missing number.

(4 + 7 +9) - (6 + x + 1) = 20-7-x = 13-x

if 13-x =0, then x = 13, which is not possible as x is a single digit

so 13 - x = 11, then x =2
