1. Divisibility by 11 is as follows :
Sum of digits at even place = 8+9+8= 25
Sum of digits at odd places = 4+4+* = 8+*
Difference= 25-8-*= 17-*
Req. difference for the no. To be divisible = 22
=> *=22-17=5
* = 5
2. Divisibility by 11 is as follows :
Sum of digits at even place = 9+3+6=18
Sum of digits at odd places = 5+7+2+* = 14+*
Difference= 18-14-* = 4-*
Req. difference for the no. To be divisible = 11
=> *= 11-4 = 7
* = 7
