Ans-Here X is the IMEI number for mobile phones. Y is the last digit of the IMEI which is a check digit calculated by Luhn's algorithm and following the same,Y comes to be '8' for 'X'.

Z represents nothing but the Chinese version of mobiles(many of them don't have the necessary unique IMEI no.).

The connection is that very recently India govt. has banned all Chinese mobiles without a valid IMEI no. flooded in India.
