The number of four-digit numbers with "distinct" digits -
Since 0 can't be used at thousand's place (that would make it a 3 digit number), we have 9 digits available for it (1 to 9). For hundred's place, 9 digits are available because 0 is now allowed. For ten's and units place 8 and 7 digits are available respectively. So value A is 9*9*8*7 = 4536.

The number of three digit numbers -
Three-digit numbers go from 100 to 999 so value B is 999-100+1 = 900.

Clearly, A is greater than B.
