The rule when rounding off numbers is "If the first figure to be discarded is 5 or more then the previous figure is increased by 1".
13.55 (2dp) can be obtained from numbers with 3 decimal places ranging from 13.545 to 13.554.
Six possibilities for the original number are 13.545, 13.547, 13.549, 13.551, 13.552, 13.554.
NOTE : If the choice of original numbers were extended to numbers having (say) 6 decimal places of figures then the six possible numbers could have been chosen from the range 13.545001 to 13.554999
