1. Step-by-step explanation:

   for divisble by 11 the rule is

   Take the alternating sum of the digits in the number, read from left to right. If that is divisible b 11 then number is also divisible by 11

   8*9484

   just asuume * as x

   now

   8-x+9-4+8-4

   25-x-8

   17-x should be divisble by 11

   17 – x = 11

   x = 6

   do same for ii also

   9-x+5-3+7-6+2

   23-9-x

   14-x=11

   x=3
